Which of the following statement does not form part of Bohr's model of the hydrogen atom?

Options

A. Energy of the electron in the orbit is quantized
B. The electron in the orbit nearest in the nucleus has the lowest energy
C. Electron revolving in different orbit have different velocities
D. The position and velocity of the electron in the orbit cannot be determined simultaneously

Explanation

To determine which statement does not form part of Bohr's model of the hydrogen atom, we will analyze each statement provided in the question.

### Step 1: Analyze the first statement
**Statement:** The energy of the electron in the orbit is quantized.

**Analysis:** According to Bohr's model, the energy of electrons in specific orbits is quantized. The formula for the energy of an electron in a hydrogen atom is given by:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
where \( n \) is the principal quantum number. This indicates that energy levels are discrete, confirming that this statement is part of Bohr's model.
