Question

What is pseudo inert gas configuration?

Answer 1

Pseudo inert gas:

• After gaining or losing an electron, the pseudo – inert gas configuration has $18$electrons instead of $8$ electrons in the ($\mathrm{n}-1$) shell electronic configuration.
• Certain elements' ions are stable because they have a perfect valence shell but lack the configuration of a noble gas.
• This is known as the pseudo noble gas configuration.

Example:

• The cuprous ion is a pseudo inert gas.
• ${\mathrm{Cu}}^{+}=1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}$
