Question

Among the ions which has smallest radius and why? a) Be2+ b)Li+ c)O2- d)F-​

Answer 1

Explanation:

Out of Li+, Be2+ and B3+ ions, which has the smallest ionic radius and why ? Looking at the periodic table we can see that the three cations have equal number of electron (after removing electrons from the neutral atoms, B, Be and Li). However, B3+ will have the smallest radius followed by Be2+ .

Answer 2

Explanation:

Out of Li+, Be2+ and B3+ ions, which has the smallest ionic radius and why ? Looking at the periodic table we can see that the three cations have equal number of electron (after removing electrons from the neutral atoms, B, Be and Li). However, B3+ will have the smallest radius followed by Be2+ .
