(writing only last couple) 3s2,3px1, 3py1, 3pz1, and not 3s2, 3px2, 3py1? Thank you

1s2 2s2 2p6 3s2 3p3; 3px1, 3py1, 3pz1. You have to fill each orbital first before you can put two electrons in one orbital, thus you go x, y, z, first.

According to Hund's rule, electrons arrange themselves to get the lowest possible energy level. While you're writing electron configurations, whenever you get to a new subshell, try putting just ONE electron in each orbital. When you get to the end of the subshell, then you can start pairing the electrons.

review the Hund's rule of multiplicity
it is written as such beacause the convention was to field all the orbitals of equal energies first with one electron before pairing...
doing so will make the atom more stable...how's that...
accdg to Hund's rule of multiplicity minimum electronic repulsion will be experienced by the three electrons in the p orbital resulting to higher stability....
best answer?
