A neutral argon atom (Z = 18)  is in its ground state electronic configuration. How many of its electrons are in the n = 3 level? __________ electrons

Explain how you arrived at your answer.

Option 1:The n = 1 level contains 8 electrons, the n = 2 level contains 2 electrons, and the n = 3 level contains 9 electrons.

Option 2: The n = 1 level contains 1 electron, the n = 2 level contains 8 electrons, and the n = 3 level contains 9 electrons.

Option 3: The n = 1 level contains 1 electron, the n = 2 level contains 6 electrons, and the n = 3 level contains 11 electrons.

Option 4: The n = 1 level contains 2 electrons, the n = 2 level contains 8 electrons, and the n = 3 level contains 10 electrons.

Option 5: The n = 1 level contains 2 electrons, the n = 2 level contains 8 electrons, and the n = 3 level contains 8 electrons.
