The ionic radii the cations monitor the exact same trends as atomic radii. They increase from height to bottom and from ideal to left in the periodic Table. Thus, the ion v the biggest radius is closest come the lower left corner of the routine Table, and also that is the K+ ion.

You are watching: Which element has the largest ionic radius


How perform you understand which atom has a larger radius?

Atomic radii differ in a predictable method across the periodic table. As can be checked out in the numbers below, the atomic radius boosts from top to bottom in a group, and also decreases from left come right across a period. Thus, helium is the the smallest element, and francium is the largest.


Which ion has biggest radius in the following?

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

Which of the following ions has actually larger ionic radius?

Hence P3− is largest amongst mentioned options.


Which is larger mg or mg2+?

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


Which has a larger atomic radius S or S2?

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


Which ion has actually the smallest radius?

As Oxygen is current at the optimal of the group, therefore, it has the smallest radius because of less number of shells.

Which ion has actually the biggest radius se2 F O2 Rb+?

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


Which that the adhering to has the largest radius?

Thus O2− has actually a minimum z-effective therefore largest radius.

Which has the biggest ionic size?

Consequently, the ion v the biggest nuclear fee (Al 3 +) is the smallest, and also the ion v the smallest nuclear fee (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 the highest value in the ion?

Which among the following ions has the highest possible value the ionic radius? This can be defined on the communication of z/e, whereby as z/e proportion increases, the dimension decreases and also when z/e proportion decreases the size increases. Z is atom number and also e is number of electrons. The correct option is C.


Is Br or Br bigger?

Br – will have actually the biggest atomic size since Br- has actually one extra electron in its valence covering which due to its unbalanced an adverse charge will be repelled and hence the atom radius that Br- will increase.

Which is bigger Mg2+ or Na+?

mg2+ would be the smaller ion this is because each ion has actually the same number of electrons but mg2+ has a greater number of protons and therefore is much more charge dense and also the outer electrons feeling a higher pull indigenous the nucleus. …


Which is smaller Mg2+ or Al3+?

As you walk from Na+ come Mg2+ to Al3+, the variety of protons in the cell core increases and also so traction the outer electrons in an ext and more. … The smallest ion will be the one with the largest variety of protons – Al3+; the biggest, the one with the least protons – N3-.
