Let"s look to the regular table for our answer! The periodic table tells us information about every aspect in existence in that is neutral state. The neutral state of an atom is as soon as it"s net fee is zero; the is, the variety of protons amounts to the number of electrons. Oxygen is the eighth element in the periodic table, v the prize O. This method that it has eight electrons in the neutral state. Since it is neutral, it also has eight protons!

The regular table has one more number connected with every element, and that is it"s atomic mass.

You are watching: Oxygen has an atomic number of 8. this means that an oxygen atom has

because that oxygen, the atomic mass is 16 AMU (Atomic mass Units). In terms of mass, protons and neutrons have about the very same mass, and also electrons have very small mass in comparison. Protons and neutrons each counting for one AMU, and the electron counts because that zero AMU. So, if the atom mass the oxygen is 16, that way we have a complete of 16 protons and neutrons. 16 complete protons and neutrons minus 8 protons leaves us v 8 neutrons.

This calculation can gain surprisingly tricky! The atomic mass of an aspect is an median over every one of the isotope of every element. An isotope is an element that has a different variety of neutrons in different atoms. The chemical properties that the element don"t change, however the atom mass that the aspect is different if the has, say, 8 neutrons versus 9 neutrons. Due to the fact that the atomic mass of each facet is average over every secure isotope of that element, sometimes we see decimal numbers because that the atomic mass. For example, the atom mass of carbon (the sixth element ~ above the regular table) is 12.01 AMU. This tells us that most carbon atoms have actually 6 protons and 6 neutrons, and also some carbon atoms have 6 protons and also maybe 7 or 8 neutrons.

Most carbon atoms have actually 6 protons and also 6 neutrons, therefore the atom mass is very close come 12 AMU. Scientists have found the family member abundance of each element and isotope, so us canlook increase how common an isotope is. For oxygen, the isotope with 8 protons and 8 neutrons makes up 99.7% of all oxygen atoms, therefore its a for sure bet come say the oxygen almost always has 8 protons and also 8 neutrons.

Answer 2:

I"ll start by answering the inquiry directly: in general, elemental oxygen has 8 protons, 8 neutrons, and also 8 electrons. Your inquiry is an amazing one, since it is regularly the beginning point for many other concerns we deserve to ask around elements, chemicals, and also materials.

For instance, though we regularly refer come the gas us breathe as simply "oxygen", that is in reality the molecule O2 (two oxygen atoms bonded together).

The factor for this needs to do through the variety of electrons oxygen has. Electrons have a certain way of arranging themselves on atoms, and we deserve to think that electrons together existing in "shells" around the atom"s nucleus. For currently we can think of atoms as having actually "inner" and also "outer" shells. Oxygen has actually an inner covering that deserve to hold 2 electrons, and an outer shell that have the right to hold 8. Shells room filled from the innermost to the outermost, for this reason since oxygen has actually 8 electrons, we put 2 in the inner shell, and also the remaining 6 in the outer shell. together we can see, there"s still two empty spots for electrons to go in the outer shell (which can hold 8), and also the oxygen would certainly really favor to to fill those spots. The does this in a clever way; it looks for a partner! If two oxygens obtain together, they have actually 16 electrons total. By "sharing" 4 the them, lock each obtain to "keep" fifty percent of the staying electrons (16 complete - 4 common = 12 remaining, 12/2 = 6 each). On each oxygen, 2 of this 6 go in the inside shell, and also the other 4 go in the outer shell. Now, the oxygens relocate close together, and also they share the 4 remaining electrons the they didn"t "keep". This means they both get to feel favor they have a complete outer covering (4 the they need to themselves, 4 that are shared in between them). This is the O2 gas the you and also I breathe!

This is just one instance of the species of points that counting electrons have the right to predict. Often, the variety of electrons in an facet can phone call us around the what color it might be, even if it is or not it"s a magnet, or what varieties of other facets it will react with. Also, if you ever before want to understand how many protons and electrons another element has, it"s as easy as looking in ~ the atomic number top top the periodic table (the big number in the height of package for every element). The number speak you the number of protons an element has, and by expansion tells friend the number of electrons it has. Elements room charge neutral (meaning the charges include up come 0), and also since protons have a confident charge, each proton is well balanced out by 1 electron, which has a an unfavorable charge. The situation with neutron (which have no charge) have the right to be a little much more complicated, yet the number of neutrons is often the exact same as or comparable to the number of protons.

Answer 3:

This is answered pretty completely on altoalsimce.org here. One refinement is to take into consideration ions, conversely, the answers at the attached question considers only neutral oxygen atoms. In general, the energy of an atom will certainly be lower, then the valence (outermost) electron covering is full. For nearly all elements, this method gaining or losing electrons to various other atoms, thus producing ions.

if the neutral oxygen atom has actually 8 full electrons, 2 are in the innermost (s) covering while the valence shell, which deserve to hold 8 electrons, has actually only 6. Thus, oxygen often tends to gain 2 electrons, because that a full of 10 electrons. This results in an atom with a net fee (i.e., one ion).

Answer 4:

In an oxygen atom, there room 8 protons and also 8 electrons. Most oxygen atoms also have 8 neutrons, however it is feasible for an oxygen atom to have 9 or 10 neutrons. They are simply rarer. The oxygen us breathe is no in atom form. That is in its molecule form, i m sorry is two oxygen atom joined with each other by bonds, and also between its 2 atoms, this molecule has 16 protons, 16 electrons, and also most frequently 16 neutrons.

Answer 5:

An oxygen atom consists of eight protons.

A neutral oxygen atom will additionally contain eight electrons, however it is feasible for an oxygen atom to it is in ionized, in which instance it will certainly have more or fewer (up to ten, or down to zero), relying on how it became ionized.

Oxygen has several isotopes, and they have various numbers that neutrons. The most typical isotope of oxygen is oxygen-16, which has eight neutrons; however, oxygen-18 is also reasonably common, and it has actually ten neutrons. Both of this isotopes room stable (i.e. Not radioactive).

Oxygen-17 (nine neutrons) is also stable, however is rarer. Having too plenty of neutrons, or as well few, will make the oxygen isotope radioactive, yet still oxygen.

Answer 6:

Oxygen is #8 in the periodic table. That method it has 8 protons and 8 electrons. The number of neutrons different according to the isotope: the secure isotopes have 8, 9, or 10 neutrons(Wikipedia).

Did you understand that this is the worldwide Year the the periodic Table - IYPT? One fun thing civilization are act is detect the element that is the same number together their age. Next year my period will be the very same number together Tungsten.

Here"s one article about the IYPT from a chemistry magazine ns get: read it here.

Answer 7:

Generally, there room 8 protons, 8 neutrons and 8 electron in the most abundant oxygen molecule. Here"s wherein it gets progressed and cool! as soon as Oxygen loses or gains neutrons it i do not care an isotope. Oxygen isotopes are seldom occurring and also have useful applications. For example, brain imaging in hospitals provides Oxygen 15, containing 7 neutrons.

Answer 8:

An oxygen atom usually has actually 8 protons, 8 neutrons, and 8 electrons. Looking in ~ the regular table, oxygen has actually atomic number 8 and also atomic load 15.999. The atomic number speak you how countless protons room in the atom"s nucleus. This identifies the atom.

because that example, if the atomic number to be 7, then the atom would certainly be nitrogen, with 7 proton in the nucleus. The atom nucleus consists of both protons and also neutrons, however the amazing thing is the there aren"t always an equal number of neutrons and protons. This info is revealed in the atom weight, which is a number that refers to the average mass that the cell core (in atomic mass units or amu). If every one of the oxygen atoms we recognize about, always had 8 protons and also 8 neutrons, climate the atomic weight would certainly be 16. Yet we understand that some forms of oxygen have fewer than 8 neutron in your nucleus, and also that is why the atomic weight is a little bit much less than 16. Oxygen"s 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge that the 8 protons. The optimistic charge of 1 proton exactly cancels the an adverse charge of 1 electron.

Answer 9:

Oxygen is atom number 8 ~ above the periodic table, which way it has 8 protons! This way that a neutral oxygen atom will have actually 8 electrons (but this number can change! because that example, throughout chemical reaction molecules deserve to lose and also gain electrons). The variety of neutrons counts on the isotope, yet a steady isotope will typically have either 8, 9, or 10 neutrons.

Answer 10:

Thanks for your question, and let’s begin with the basics: exactly how chemical facets aredefined, particularly on the routine table of elements.

The major, whole numbers over the aspects on the periodic table of facets (you’veprobably checked out one in your science instructor’s room) determine the element and it refers to the variety of protons as a definitional part of the element’s identity. That’s the lengthy version of this basic fact: oxygen will constantly have 8 protons, whether on Mars, Pluto, Earth, yesterday, or the work after tomorrow.Next, let’s take into consideration the variety of neutrons and electrons in oxygen: in short, they’rechangeable within natural constraints. In the case of neutrons, oxygen has various isotopes, i beg your pardon are different versions that oxygen that maintain their variety of protons, but readjust their variety of neutrons. In our scientific observations, oxygen has actually either 8, 9, or 10 neutrons.

Now, in terms of electrons, oxygen must contain 8 electrons in stimulate to be isoelectric, which is a way of speak the electrons equal the number of protons, rendering no charge to the oxygen atom, and this is thought about the most organic state of the oxygen atom (you can “add”/”subtract”electrons through high energy collisions with particle accelerators, yet that’s more artificial, anddepending ~ above the referral point, oxygen deserve to “gain” electrons throughout molecular bonding).
