Give two points of distinction between charge and mass.

Explanation

### Step-by-Step Solution:

1. **Understanding Charge**:
- Charge can exist in three forms: positive, negative, or neutral (zero). This means that objects can have a surplus of electrons (negative charge), a deficit of electrons (positive charge), or an equal number of protons and electrons (neutral).

2. **Understanding Mass**:
- Mass, on the other hand, is a measure of the amount of matter in an object. It is always a positive quantity and cannot be negative or zero. Every physical object has mass, and it represents the resistance of the object to acceleration when a force is applied.
