Question

Write two isoelectronic of − and –ions.

Answer 1

Answer:

Some of its isoelectronic species are Na+ ion (11 – 1 = 10 electrons), Ne (10 electrons), O2– ion (8 + 2 = 10 electrons), and Al3+ ion (13 – 3 = 10 electrons). (ii) Ar has 18 electrons. Thus, the species isoelectronic with it will also have 18 electrons.
