Answer #1

A. An element with the valence electron configuration 3s1 would form a monatomic ion with a charge of_+1____ . In order to form this ion, the element will_lose___ one___electron from the__3s_subshell(s).

The element is sodium. When it loses one electron, it forms inert gas configuration of neon.This results in stability.

B. If an element with the valence configuration 4s13d10 loses 1 electron, this electron would be removed from the __4s____subshell.

The element is copper. Electron is removed from 4s subshell. 3d subshell is completely filled. This leads to stability.
