Given, a monoatomic ion with charge of -2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6
Since, the charge on the monoatomic ion is negative (-2) so, the ion is an anion.
The electronic configuration of the ion given is 1s2 2s2 2p6 3s2 3p6 . There are total 18 electrons in the ion. The noble gas which has 18 electrons is Argon.
Electronic configuration of Argon (18) : 1s2 2s2 2p6 3s2 3p6
Therefore, the ion is isoelectronic with Argon (Ar).
The ion is monoatomic, which means it contains only one atom and has a charge of -2.
The electronic configuration of the ion given is 1s2 2s2 2p6 3s2 3p6 .
There are total 18 electrons in the ion.
The atom in neutral state will have 2 electrons less than that of the i...
