**Quantum Numbers and Electron Configuration**

This section addresses how to determine the number of electrons in an atom based on specific sets of quantum numbers. Quantum numbers are a set of values that describe the unique quantum state of an electron in an atom. The relevant quantum numbers are:

1. **Principal Quantum Number (n)**: Indicates the shell or energy level of an electron. Higher values of \( n \) mean higher energy levels and distance from the nucleus.

2. **Angular Momentum Quantum Number (\( \ell \))**: Defines the shape of the orbital. It can range from \( 0 \) to \( n-1 \).

3. **Magnetic Quantum Number (\( m_\ell \))**: Specifies the orientation of the orbital in space. It ranges from \(-\ell\) to \(+\ell\).

4. **Spin Quantum Number (\( m_s \))**: Indicates the spin direction of the electron, which can be \( +\frac{1}{2} \) or \(-\frac{1}{2} \).

---

### Questions:

1. **\( n = 2 \)**
   - How many electrons can exist in the second energy level?

2. **\( n = 5, \ell = 2 \)**
   - How many electrons can occupy the 5d subshell?

3. **\( n = 7, \ell = 2, m_\ell = -1 \)**
   - How many electrons can exist in a specific orbital of the 7d subshell with a given orientation?

---

By analyzing these quantum numbers, students will learn how to apply the Pauli exclusion principle and Hund's rule to determine electron configurations and understand orbital filling strategies within an atom.
