How do you make 58.703 into having 3 dig figs ?

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
