Alina [70]

Answer : Option C) The Octet Rule

Explanation : Atoms have a tendency to complete their outer energy level. This is known as Octet Rule.

The octet rule is a chemical rule of thumb which reflects the observation, that atoms of main-group elements tends to combine in such a way that each atom gets eight electrons in its valence shell, which gives it the same electron configuration as that of a noble gas.

In short, the tendency of an atom to fill its valence shell and attain a stable state it acquires or donates the electron is called as octet rule.
