Detailed explanation-1: -The octet rule states that an atom tends to have eight electrons in its outermost valence shell by forming covalent bonds through gaining or losing electrons from its outermost shell. Elements that obey octet rules are the main group elements which are oxygen, carbon, nitrogen.

Detailed explanation-2: -The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.

Detailed explanation-3: -In the formation of a chemical bond, atoms lose, gain or share valence electrons to complete their outer shell and attain a noble gas configuration. This tendency of atoms to have eight electrons in their outer shell is known as the octet rule.

Detailed explanation-4: -The Octet Rule: The atoms that participate in covalent bonding share electrons in a way that enables them to acquire a stable electron configuration, or full valence shell. This means that they want to acquire the electronic configuration of the noble gas of their row.

Detailed explanation-5: -However, there are three general exceptions to the octet rule: Molecules, such as NO, with an odd number of electrons; Molecules in which one or more atoms possess more than eight electrons, such as SF6; and. Molecules such as BCl3, in which one or more atoms possess less than eight electrons.
