Question

The noble gas core together with $(n-1)d^{10}$ electrons is called pseudo-noble gas core.

• A. True
• B. False

Answer 1

The correct option is A True

Pseudo-noble gas refers to elements having 18 electrons instead of just 8 in their outermost electron configuration when they lose or gain electrons.
So they have configuration $n{s}^{2}n{p}^{6}n{d}^{10}$.
