What should be the maximum velocity of an electron orbiting around a hydrogen nucleus

Explanation

To find the maximum velocity of an electron orbiting around a hydrogen nucleus, we can use the formula derived from Bohr's atomic model. Here’s a step-by-step solution:

### Step 1: Understand the formula for the velocity of an electron
The velocity \( v \) of an electron in a hydrogen atom is given by the formula:
\[ v = \frac{2.18 \times 10^6}{n} \text{ m/s} \]
where \( n \) is the principal quantum number.
