An orbital being full or half full is good (lower in energy - d orbitals) l=0, s orbital (sphere) l=1 p orbital (dumbbell shape) l=2 d orbital (2 p orbitals together, x shape) l=3 f orbital l=4 g orbital n=1, l=0 is called 1s n=2, l=0 is called 2s n=2, l=1 is called 2p n=3, l=2 is called 3d 1s^2 means 2 electrons are in the 1s orbital 3d^7 means 7 electrons are in the 3d orbital
