Sodium metal vaporises on heating and the vapour will have diatomic molecular of sodium `(Na_(2))`. What type of bonding is presetn in these moleculas ? Justify your answer .

Explanation

To determine the type of bonding present in diatomic sodium (Na₂) molecules, we can follow these steps:

### Step 1: Identify the Nature of Sodium
Sodium (Na) is an alkali metal with one electron in its outermost shell (3s orbital). When sodium vaporizes, it forms diatomic molecules (Na₂).

### Step 2: Understand the Bonding in Na₂
In Na₂, two sodium atoms come together to form a molecule. The bonding between these two atoms can be analyzed using the concept of covalent bonding.
