Confusion regarded e- configuration

Postby welcometochillis » Sun Oct 29, 2017 6:28 pm

Do you go through the energy levels first or do you go through orbitals first. for examples ig writing a notion that is 3s3d3p or do you write it 1s2s3s1d2d3d4d??

its done through energy level so it should be 1s 2s 2p 3s 3p 3d 4s 4p, etc. the d comes after the p.
Of course, you can substitute a noble gas in the notation to make it shorter, e.g. Ni = [Ar] 3d^8 4s^2

It's done by energy level because that's the order in which the electrons fill the orbitals. They go up the energy levels instead of jumping up and down them to get to the same orbitals

Also what is the difference between the Hund's principle and Pauli Exclusion principle and how does it effect e- configuration?
