How do not the energy of orbits in an atom vary?

Explanation

To answer the question "How do not the energy of orbits in an atom vary?", we can break down the explanation into several clear steps:

### Step-by-Step Solution:

1. **Understanding Atomic Orbits**:
- In an atom, electrons move in specific paths called orbits or energy levels. These orbits are not randomly distributed but are quantized, meaning they have fixed sizes and energies.

2. **Niels Bohr's Model**:
