The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
The electron configuration of phosphorus is [Ne]3s2.3p3.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6

The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê

Lithium has one valence electron. It is much easier for an atom to lose one electron than gain seven more. Lithium looses this one electron to achieve a full outer shell (the next inside shell is full).
