The 4 is from the 4th shell. Both s blocks are filled so it is 4s2.It is the fourth block in the p subshell so it is 4p4 The 1st d subshell is actually in shell 3 and all 10 blocks are filled, so its 3d10. Whenyou put them in order, it is [Ar] 3d10 4s2 4p4.

Hello. Thanks My question is why 3d first before 4s? Thought 4s has a lower energy level than 3d?

The 4s has Lowe energy than 3D but when giving the electron configuration, list the electrons in the s, p, d, and f order
