Explanation:

For \(1s^2 2s^2 2p^6\):

Step 1: Calculate total electrons

Sum the exponents: \(2 + 2 + 6 = 10\).

Step 2: Identify element

Atomic number 10 is Neon (\(Ne\)).

For \(1s^2 2s^2 2p^6 3s^2 3p^3\):

Step 1: Calculate total electrons

Sum exponents: \(2 + 2 + 6 + 2 + 3 = 15\).

Step 2: Identify element

Atomic number 15 is Phosphorus (\(P\)).

For \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^1\):

Step 1: Calculate total electrons

Sum exponents: \(2 + 2 + 6 + 2 + 6 + 1 = 19\).

Step 2: Identify element

Atomic number 19 is Potassium (\(K\)).

For \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8\):
