That is the element phosphorous
Sulfur is the group 16, period 3 chemical element. Thus, its electron configuration is 1s2 2s2 2p6 3s2 3p4. Another way to write this is [Ne] 3s2 3p4 since the initial portion of the configuration is the same as neon's.

1s2, 2s2 2p6, 3s2 3p1or[Ne], 3s2 3p1
Argon
The investigator will find that 1s2 2s2 2p6 is the electron configuration for neon.
1s2 2s2 2p6 3s2 3p6 is the electron configuration of chlorine
Potassium is the group 1, period 4 element on the periodic table. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1. This can be shortened to [Ar] 4s1 because argon's electron configuration is 1s2 2s2 2p6 3s2 3p6.
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5
1s2 2s2 2p6 3s2 3p 4s2
