Question

What ions are isoelectronic with neon?

Answer 1

You can get an ion that is isoelectronic with neon by either `"OXIDATION"` or `"REDUCTION..........."`

Explanation:

Neon has (`Z=10`) has 8 valence electrons, and a full valence shell. Looking at the Periodic Table, reduction gives the anions, `F^-, O^(2-), N^(3-)` as isoelectronic species.

Equivalently, oxidation gives `Al^(3+), Mg^(2+), Na^(+)` as isoelectronic ions. Are you clear on the context I use with respect to `"oxidation"` and `"reduction.........?"`

As is typical, the metals, electron rich species, have been oxidized, whereas the non-metals, electron poor species due to higher nuclear charge, have been reduced.
