Baking soda has a ph of 9, and household ammonia has a ph of 12. this means that ammonia is times more basic than baking soda.

Ammonia would be 3 times more basic its higher up on the pH scale

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.
