What is the valence shell? It is the outermost shell of electrons in an atom. It is the same as the orbital configuration. It is the last partially filled orbital in an atom. It is the shell of electrons in element V (atomic no. = 23) It is the shell of electrons in an atom that is the least reactive.
How many electrons will be in the valence shell of non-H atoms when they make covalent bonds?
Because of the number of valence electrons (determined above], how many electrons will the lose or gain or what charge will the given elements most likely have? Also indicate the number of bonds each atom will most likely make due to the number of valence electrons.
