What do you mean by electrostatic force? Explain why it is easier to separate the electrons from it.

Explanation

### Step-by-Step Solution:

1. **Definition of Electrostatic Force**:
The electrostatic force is the force that attracts or repels charged particles due to their electric charge. In the context of an atom, it is the force that holds the negatively charged electrons in orbit around the positively charged nucleus (which consists of protons and neutrons).

2. **Structure of an Atom**:
An atom consists of a nucleus at its center, which contains protons (positively charged) and neutrons (neutral). Electrons (negatively charged) revolve around this nucleus in specific orbits.
