Answer:
It's B
Step-by-step explanation:
at ground state the atomic number or proton number is equal to the electron number
Normally
the trend for electronic configuration goes as
1s² - 2S² - 2P⁶ -3S² - 3P⁶ -4S² - 3D¹⁰ and so on
(with each number representing a particular energy level and we go from lower to higher energy level)
but for this case we have sulfur
so we go from
1s² - 2S² - 2P⁶ - 3S² - 3P⁴ (I think that was what was supposed to be there not just 2P)
you fill from the lowest energy level to the highest and stop filling when you run out of electrons
since we only had 16 electrons I stopped at 3P⁴
