The ionic radii that cations monitor the exact same trends as atomic radii. They rise from peak to bottom and also from right to left in the routine Table. Thus, the ion with the largest radius is closest come the lower left edge of the regular Table, and that is the K+ ion.

You are watching: Which ion has the largest atomic radius


How perform you know which atom has a larger radius?

Atomic radii vary in a predictable method across the routine table. As deserve to be watched in the numbers below, the atom radius increases from optimal to bottom in a group, and also decreases from left come right across a period. Thus, helium is the smallest element, and francium is the largest.


Which ion has best radius in the following?

=34)>Rb+(A. N. =37) electrons) ∴Se2− has actually largest radius.

Which the the complying with ions has actually larger ionic radius?

Hence P3− is largest amongst mentioned options.


Which is bigger mg or mg2+?

Answer. Therefore Mg atom will be larger as the has much more electrons 보다 Mg 2+ and also thus will have actually larger atom radii.


Which has a larger atomic radius S or S2?

(ii) describe why the radius of the S2- ion is larger than the radius the the S atom. The nuclear fee is the same for both species, however the eight valence electrons in the sulfide ion experience a better amount the electron-electron repulsion than perform the 6 valence electrons in the neutral sulfur atom.


Which ion has actually the the smallest radius?

As Oxygen is existing at the height of the group, therefore, it has actually the the smallest radius because of less variety of shells.

Which ion has the largest radius se2 F O2 Rb+?

Answer. Answer: The prize is “Rubidium Rb+”.


Which the the complying with has the largest radius?

Thus O2− has a minimum z-effective for this reason largest radius.

Which has the largest ionic size?

Consequently, the ion v the greatest nuclear fee (Al 3 +) is the smallest, and also the ion v the the smallest nuclear charge (N 3−) is the largest.…Ionic Radii and Isoelectronic Series.


IonRadius (pm)Atomic Number
N 3−1467
O 2−1408
F −1339
Na +9811

What has actually the greatest value in the ion?

Which among the following ions has actually the highest possible value of ionic radius? This can be explained on the basis of z/e, whereby as z/e ratio increases, the dimension decreases and when z/e ratio decreases the dimension increases. Z is atomic number and also e is variety of electrons. The correct alternative is C.


Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in the valence covering which because of its unbalanced an unfavorable charge will certainly be repelled and hence the atomic radius that Br- will increase.

Which is enlarge Mg2+ or Na+?

mg2+ would certainly be the smaller ion this is due to the fact that each ion has the same variety of electrons yet mg2+ has a greater variety of protons and also therefore is more charge dense and also the outer electrons feel a better pull from the nucleus. …


Which is smaller Mg2+ or Al3+?

As you go from Na+ come Mg2+ to Al3+, the variety of protons in the cell core increases and also so traction the external electrons in much more and more. … The smallest ion will certainly be the one v the largest variety of protons – Al3+; the biggest, the one through the least protons – N3-.
