`Mg^(+2)` is smaller than `O^(-2)` in size, though both have same electronic configuration - explain.

Mg^(2+) is smaller than O^(2-) in size, throgh both have same electronic configuration. Explain?

Mg^(2+) is smaller than O^(2-) in size, throgh both have same electronic configuration. Explain?

Mg^(2+) ion is smaller than O^(-2) ion although both have same electronic configuration. Why ?

Why Mg^(2+) ion is smaller than O^(2-) althrough both have the same electronic configuration ?

Mg^(+2) ion is smaller than O^(-2) ion in size though both are iso electronic -Explain.

Account for the following : Mg^(+2) is smaller than O-^(2) ion although both have same electronic structure . (ii) Ionisation enthalpy of nitrogen is more than that of oxygen .

The pair of ions having same electronic configuration is

Na^(+) has higher value of ionization energy than Ne, though both have same electronic configuration - Explain.

What is the electronic configuration of O^(2-) ion?
