Final answer:
Sulfur has 16 electrons distributed over four energy levels, with each energy level containing a different number of electrons.
Step-by-step explanation:
The valence electron configuration of sulfur is [Ne]3s²3p4. This means that sulfur has a total of 16 electrons. The electrons are distributed over four energy levels: the 1s, 2s, 2p, and 3s energy levels. Each energy level can hold a certain maximum number of electrons based on the formula 2(n)^2, where n is the principle energy level. The first energy level (1s) can hold 2 electrons, the second energy level (2s) can hold 8 electrons, the second energy level (2p) can hold 6 electrons, and the third energy level (3s) can hold 2 electrons.
