Question

A. An element with the valence electron configuration 5s2 5s5 would form a monatomic ion with a charge of_____ . In order to form this ion, the element will____ (lose/gain) _____electron(s) from/into the_____ subshell(s).

Answer 1

I think you meant 5s²5"p"⁵.

An element with the valence electron configuration 5s² 5p⁵ would form a monatomic ion with a charge of -1 . In order to form this ion, the element will gain (lose/gain) 1 electron(s) from/into the 5p subshell(s).
