Explanation / Answer
Part 1
A. A main group element with the valence electron configuration 5s2 is in periodic group .
It forms a monatomic ion with a charge of +2
Example = Sr+2 ion
B. A main group element with the valence electron configuration 2s22p4 is in periodic group .
It forms a monatomic ion with a charge of -2.
example = O-2
Part 2
A. An element with the valence electron configuration 5s2 would form a monatomic ion with a charge of +2.
In order to form this ion, the element will _(lose)____(losegain) _(2)__(12345678) electron(s) from/into the __(s)subshell_____(spdfs + ps + dp + d subshell(s).
B. An element with the valence electron configuration 2s22p5 would form a monatomic ion with a charge of -1.
In order to form this ion, the element will _(gain)____losegain _(1)__12345678 electron(s) from/into the _(p)subshell______(spdfs + ps + dp + d subshell(s)).
