Here are answers to 2022-2023 Review Homework for Electron Configurations, Atomic Mass and Periodic Table
1) Fill completely with electrons the first subenergy (closest to nucleus therefore least amount of energy those electrons have)
2) Electrons. The way we says it is maximum 2 electrons in each orbital.
3) Electrons are filled into each orbitals (also called degenerate) before any orbital can have two electrons in it.
4) 3 subenergy levels ("s", "p", and "d") subenergy level.
5) There are 5 "d" orbitals in each "d" subenergy level
6) Since there are two different types of subenergy levels, s brings 2 electrons and p orbital brings 6 for a total of 8electrons.
