    Answer:

    The first ring can fit 2 valance electrons the 2and 3rd ring can fit 8 valance elctrons. The substances want to be eaual.

    Explanation:

    Octect rule - Atoms need 8 valance electrons to become stable (you need 8 to be great).

    Enert - Noble Gasses don't bond because they already have 8 valance electrons.

    Metals-lose electrons-Cation

    Non metals-gain electrons-Anion

    Bonds occur due to the transfer of valence electrons lost/gained.

    Ionic bonds-One of many occur between meets and non metals.
