A metal in group 16 of the periodic table can become a chemically stable ion by

Answer 1

Answer : A metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.

Explanation :

The group 16 element are oxygen, sulfur, selenium, tellurium and polonium.

The general electronic configuration of group 16 elements is, $ns^2np^4$

As we now that there are total 6 electrons in p sub-shell. So, a metal in group 16 can become a chemically stable ion by gaining 2 electrons.

$M+2e^-\rightarrow M^{-2}$

Hence, a metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.
