sublevel # of electrons in each sublevel s 2 p 6 d 10 f 14 g 18

The Principal power Level (the #) just holds the # that sublevels.

 Principal power Level # of Sublevels sublevels 1 1 1s 2 2 2s 2p 3 3 3s 3p 3d 4 4 4s 4p 4d 4f 5 5 5s 5p 5d 5f 5g

Yes, the 5th energy level holds 5 sublevels and that critical one would be 5g.

Electrons add in energy order (Aufbau Principle) not energy level order.

Sublevels are broken down into orbitals

an orbital holds 2 electrons

Here is an animation of how the orbitals would look as you construct out from the 1s.Pauli exclusion PrincipleWhen we attract electrons, we usage up and down arrows. So, if an electron is combine up in a box, one arrowhead is up and also the 2nd must be down.Hund’s ascendancy

When filling sublevels other than s, electrons are put in individual orbitals before they space paired up.
