How many unpaired electrons does an atom of sulfur have in its ground state?

1 Answer

#2# electrons

Explanation:

Its configuration will be

#"S: " 1s^2 2s^2 2p^6 3s^2 3p^4#

The p subshell can accommodate a maximum of #6# electrons, but here it holds 4 electrons, which means that sulfur has #2# unpaired electrons, both located in the p-subshell.

Sulfur will have a pair of electrons in the 1st #3p# orbital, 1 electron in the 2nd #3p# orbital, and 1 electron in the 3rd #3p# orbital.
