The electron configuration of an atom tells us how many
electrons are in each orbital. For example, helium has two
electrons in the 1s orbital. Therefore the electron
configuration of He is 1s2
part a:
What is the ground-state electron configuration of a neutral
atom of nickel?
Express your answer in condensed form, in order of increasing
orbital energy. For example, [He]2s22p2 would be
entered as [He]2s^22p^2 .
part b:
What is the ground-state electron configuration of the oxide ion...
