sample of nickel is found to have a magnetization of 460600.00 A/m. What fraction of the nickel atoms in the sample have their magnetic moments aligned

D.na is the answer hope this

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.
