Question

Consider the given species: N³⁻, O²⁻ , F⁻, Na⁺, Mg²⁺ and Al³⁺ Arrange them in the order of increasing ionic radii.

Answer 1

Al3+,N³⁻, O²⁻ , F⁻, Na⁺, Mg²⁺

Answer 2

"The more positive the charge is, the smaller the ionic radius will be.

When electrons are added, these particles go in the outside shells.

Also, when an atom falls electrons, it clings more tightly to the 1 it has left, besides decreasing the ionic radius.

For the order of ionic radii will be as follows

AL3+ Mg2+ Na+ F- O2- N3- (increasing order)
