Explanation:

1. First, find chlorine's atomic number: Chlorine (Cl) has an atomic number of 17, meaning a neutral chlorine atom has 17 electrons.
2. Follow the aufbau principle to fill orbitals in order: 1s, 2s, 2p, 3s, 3p.
3. Fill each orbital to its maximum capacity: 1s holds 2, 2s holds 2, 2p holds 6, 3s holds 2. The remaining 5 electrons go to 3p.
4. Sum the exponents: $2+2+6+2+5=17$, which matches the total number of electrons. Eliminate options that skip orbitals, have incorrect orbital filling order, or the wrong total number of electrons.

Answer:

$1s^2 2s^2 2p^6 3s^2 3p^5$ (the second option)
