The element "S" refers to sulfur. The atomic number of sulfur is 16, meaning it has 16 electrons. The electron configuration for sulfur is: \[ 1s^2 2s^2 2p^6 3s^2 3p^4 \] This corresponds to the first option, which shows sulfur's correct electron configuration.
The correct option is (A): \(1s^2 2s^2 2p^6 3s^2 3p^4\)
