How many electrons are in the 2nd principle energy level (n = 2) of aphosphorus atom?
Question
Solution 1
A phosphorus atom has 15 electrons in total. The electron configuration of a phosphorus atom is 1s² 2s² 2p⁶ 3s² 3p³.
The 2nd principle energy level (n = 2) includes the 2s and 2p sublevels.
The 2s sublevel has 2 electrons and the 2p sublevel has 6 electrons.
