Electon Lab Configuration continued

We also discussed why the 3d orbital fills up before the 4p.  The students drew calcium with an electron configuration ending in 4s2.  Then, the students drew scandium, which ends in 3d1.








The 3rd energy level or ring can hold up to 18 electrons.  After the first 8, the 4s orbital is filled before the final 10 of the 3rd energy level are filled in.

 The following is a list of the configurations of the first 54 elements.  The color indicates whether the electrons are in the s, p or d orbitals.
