Classify the following elements as metals, non metals and inert gases and give reasons in support of your answer.
Chlorine, Magnesium, Argon, Phosphorus, Potassium, Sulphur, Neon

Explanation

To classify the elements Chlorine, Magnesium, Argon, Phosphorus, Potassium, Sulphur, and Neon as metals, non-metals, and inert gases, we will analyze their properties and electronic configurations.

### Step-by-Step Solution:

1. **Chlorine (Cl)**
- **Classification**: Non-metal
- **Reason**: Chlorine has an atomic number of 17, with an electronic configuration of 2, 8, 7. It has 7 valence electrons and tends to gain 1 electron to achieve a stable octet configuration (8 electrons in the outer shell).
