You can find valence electrons with a shortcut using the periodic table, but it’s good to only do that after you understand why the shortcut works, and to do that you have to draw out the full electrons and orbitals for a few different atoms. Valence electrons are just electrons in the last orbital, they are different from core electrons, which are the total number of electrons except the valence.
