Explanation / Answer

Number of electrons = 2 x n^2 (where n is quantum number)

Quantum number 1 => 2 x 1^2 = 2 electrons

Quantum number 2 => 2 x 2^2 = 8 electrons

Quantum number 3 => 2 x 3^2 = 18 electrons

Quantum number 4 => 2 x 4^2 = 32 electrons

Quantum number 5 => 2 x 5^2 = 50 electrons

Quantum number 6 => 2 x 6^2 = 72 electrons
