Differentiate between metal and non-metal on the basis of their chemical properties.

Explanation

To differentiate between metals and non-metals based on their chemical properties, we can follow these steps:

### Step 1: Electropositivity vs. Electronegativit
- **Metals**: Metals are generally electropositive, meaning they tend to lose electrons during chemical reactions. This is due to their low ionization energies.
- **Non-metals**: Non-metals are typically electronegative, which means they tend to gain electrons to achieve a stable electron configuration (octet).

### Step 2: Reaction with Oxygen
- **Metals**: When metals react with oxygen, they form basic oxides. For example, magnesium (Mg) reacts with oxygen (O₂) to form magnesium oxide (MgO), which is basic in nature.
