The formation of O2 molecule by Lewis theory is as follows:
- Lewis's theory is based upon the completion of octet either by complete transfer or sharing of electrons.
- Oxygen has atomic no 8.
- In its outer shell, there are 6 electrons.
- So, it needs 2 electrons to complete its octet.
- Two oxygen atoms share two of their electrons with each other.
- In this way, they form a double bond.
- Now both of them have completed their octet by sharing 2 electrons.
- Hence the molecule O2 is formed.
