Sure, here's a step-by-step description of the bonding in a molecule of oxygen (O2):

1. Oxygen is the 8th element on the periodic table, which means each oxygen atom has 8 electrons. Two of these electrons are in the inner shell (K shell), and the remaining six are in the outer shell (L shell).

2. The outer shell can hold a maximum of 8 electrons. So, each oxygen atom needs two more electrons to complete its outer shell.

3. In a molecule of oxygen (O2), two oxygen atoms share a pair of electrons in a covalent bond. This means each oxygen atom shares one of its six outer shell electrons with the other oxygen atom.

4. However, oxygen atoms actually form a double covalent bond, meaning they share two pairs of electrons. This happens because each oxygen atom still has one unpaired electron after forming the first covalent bond, so they form a second bond by sharing another pair of electrons.

5. This double bond is very strong and makes O2 a stable molecule. The two shared pairs of electrons are often represented as a double line (=) between the two oxygen atoms (O=O).

6. In addition to the double bond, each oxygen atom also has two lone pairs of electrons that are not involved in bonding. These lone pairs repel each other and the shared pairs, giving the molecule a bent shape.

7. The double bond and lone pairs of electrons also give oxygen molecules their properties, such as being a gas at room temperature and having the ability to support combustion.
