      All elements in this group tend to lose their valence electrons. This oxidation state means that no electrons were lost and four were gained from another element. Will magnesium lose or gain electrons? Magnesium is in Group II and has two electrons in its valence shell. Thus it tends to lose two electrons.

    Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
    • The number of valence electrons is the number of electrons in the outer shell of an atom. To determine the valence electron configuration of an element, you first select select the nearest noble gas preceding the element. For nickel, this would be argon. The electron configuration of Ni can thus be expressed as that of Ar plus 10 valence electrons.
    • Each of their atoms contains two valence (outermost) electrons. After an element has 8 valence electrons, it will add electrons to a new orbital (this is what Ba does) It would need to gain 6 valence electrons to have 8, or it can lose 2 valence electron in order to have 8.
