the outer shell - which 'wants' to be full.
The total number of electron shells in an atom has determines its period grouping.
It's outer valence electron shell(s).
The valance shell is important in chemical reactions, as it is the valance electrons which are gained/lost during reactions. An atoms valance electron configuration is what largely determines its chemical reactivity.
The oxidation state of an element is determined by the number of electrons the element needs to lose or gain to have a full valence electron shell.
by the number of electrons in its outermost shell
The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom
The electrons in the outermost shell
The valence shell containing the valence electrons used in chemical reactions.
The total number of electron shells in an atom has determines its period grouping.
It's outer valence electron shell(s).
