Explain the formation of (i) oxygen molecule and (ii) ethylene molecule with the help of Lewis dot structure.

Explanation

To explain the formation of (i) an oxygen molecule (O₂) and (ii) an ethylene molecule (C₂H₄) using Lewis dot structures, we will follow these steps:

### Formation of Oxygen Molecule (O₂)

1. **Identify the Molecular Formula**: The molecular formula for an oxygen molecule is O₂.

2. **Determine Valence Electrons**: Each oxygen atom has 6 valence electrons. Therefore, for two oxygen atoms, the total number of valence electrons is:
\[
