octet rule

Let us learn about octet rule.

The octet rule indicates that atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell. It is useful rule but we should also know that there are many bonding situations where it does not apply.

The octet rule turns out to be violated almost as much as it is followed. The octet rule comes from the realization that since atoms wants to have noble gas structure and some noble gases have eight electrons in their valence shell, atoms should have eight electrons around them.

The atoms that commonly follow the octet rule are

• Carbon: C
• Nitrogen: N
• Oxygen: O
• The halogens, F, Cl, Br, I
  
• 
  

Each of these above atoms will probably have 8 electrons around it.
