Compare metals and non-metals based on the following properties
(i) Electrical conductivity
(ii) Tensile strength
(c) Formation of ions
(iv) Reaction with acids

Explanation

To compare metals and non-metals based on the given properties, we can create a structured table that highlights the differences clearly.

### Step-by-Step Solution:

1. **Electrical Conductivity:**
- **Metals:** Metals are good conductors of electricity. This is due to the presence of free-moving electrons that can carry electric current.
- **Non-Metals:** Non-metals are generally poor conductors of electricity, with the exception of graphite, which can conduct electricity due to its structure.
