Question

In order for a nonmetal to obey the octet rule, it____.

A.gains protons
B.loses electrons
C.gains electrons
D.loses protons

Answer 1

Answer: C. gains electrons.

Explanation:

• Octet rule states that "it is the tendency of the atom to have eight electrons in its outermost valence electron shell".

• Nonmetals obey octet rule by gaining electrons to its outermost valence electron shell.

• For example: Cl which has 17 electron and its electronic configuration is 2,8,7 and it gain electron to have 8 electrons in its outermost electron shell to form Cl⁻ with electronic configuration of 2,8,8.
