Which of the following statement is //are wrong ?

Options

A. If the value of `l = 0`, the electron distribution in spherical
B. The shape of the orbital is given by magnitic quantum number
C. The angular momentum of `1s 2s and 3s` electron are equal
D. In an atom all electron travel with the same velocity

Explanation

To determine which of the statements is wrong, we will analyze each statement one by one based on our knowledge of atomic structure and quantum numbers.

### Step-by-Step Solution:

1. **Statement Analysis:**
- **Statement 1:** "If the value of l is equal to zero, then the electron distribution is spherical."
- The azimuthal quantum number \( l \) determines the shape of the orbital. When \( l = 0 \), it corresponds to the s orbital, which indeed has a spherical shape.
- **Conclusion:** This statement is **correct**.
