What three methods are used to represent the arrangement of electrons in atoms ?

Question

Electron Configuration. I need it for help with my HW please.

Answer 1

you can also write 1s2 2s2 2p4, for instance. In this way you are telling the number of electrons in each energy level (orbital), being 1s, 2s and 2p in this example the orbitals and being the number at the right the quantity of electrons there.

Answer 2

Lewis structure, electron dot diagram, and you can use models...not sure if those are what you're looking for.
