32 Which electron configuration represents the electrons in an atom of sulfur in an excited state? (1) 2 – 8 – 6
(2) 2 – 7 – 7
(3) 2–8– 7
(4) 2–7– 8
Solution: The electron configuration for sulfur in its most stable, ground state can be found on the Periodic Table. It is 2-8-6. When an electron gets excited, it goes to the higher energy level. For example, 2-7-7, means that the electron from the second level jumped to the third level.
