For a helium atom in its ground state, what are quantum numbers `(n,l,m_(l)andm_(s))` for the (a) spin-up electron and (b) spin-down electron?

Explanation

To determine the quantum numbers for the electrons in a helium atom in its ground state, we need to identify the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s) for both the spin-up and spin-down electrons.

### Step-by-Step Solution:

1. **Identify the Principal Quantum Number (n)**:
- For a helium atom in its ground state, the principal quantum number \( n \) is 1. This indicates that the electrons are in the first energy level.

**Hint**: The principal quantum number indicates the energy level or shell of the electron.
