Name any two basic properties of electric charge.

Explanation

### Step-by-Step Solution:

1. **Understanding Electric Charge**: Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It exists in two types: positive and negative.

2. **First Property - Quantization of Electric Charge**:
- This property states that electric charge is quantized. This means that the total charge of any body is always an integral multiple of a basic unit of charge.
- Mathematically, this can be expressed as:
\[ q = n \cdot e \]
where:
- \( q \) is the total charge,
- \( n \) is an integer (0, 1, 2, ...), and
- \( e \) is the elementary charge (the charge of a single electron, approximately \( 1.6 \times 10^{-19} \) coulombs).

3. **Second Property - Conservation of Charge**:
- This property states that electric charge can neither be created nor destroyed.
- Instead, the total charge in an isolated system remains constant over time.
- This means that the sum of charges before any interaction is equal to the sum of charges after the interaction.

### Summary of the Two Basic Properties:
1. **Quantization of Electric Charge**: Total charge is an integral multiple of elementary charge.
2. **Conservation of Charge**: Charge cannot be created or destroyed; it remains constant in an isolated system.
