If n = 5, how many electrons can have `m_(l) = +1`?

Explanation

To solve the question, "If n = 5, how many electrons can have \( m_l = +1 \)?", we will follow these steps:

### Step 1: Identify the Principal Quantum Number (n)
The principal quantum number \( n \) is given as 5. This indicates the energy level of the electrons in the atom.

### Step 2: Determine the Possible Values of the Azimuthal Quantum Number (l)
The azimuthal quantum number \( l \) can take values from 0 to \( n-1 \). Therefore, for \( n = 5 \):
- Possible values of \( l \): \( 0, 1, 2, 3, 4 \)
