The electron configuration for [Ne] or 1sS1U1P12S1S1P02sS1U1P12S1S1P02pS1U1P16S1S1P0 represents the ground-state electron configuration for AlS1U1P13+S1S1P0. This configuration includes the noble gas configuration for neon ([Ne]), followed by the electron configuration for aluminum ([Ne]3sS1U1P12pS1U1P1), and finally the electron configuration for sulfur ([Ne]3sS1U1P23pS1U1P4). The electron configuration for the 1s orbital is also included for completeness. The other answer choices either include incorrect subshells or incorrect numbers of electrons in certain subshells.
