The Public Comment period, held at 2:30 p.m. or shortly thereafter, is separate from public hearings on specific agenda items. Citizens interested in making public comments should sign up to speak prior to 2:30 p.m. Speakers during public comments should limit their remarks to three minutes. The Commissioners want to hear all the citizens' comments.
Most atoms need 8 electrons to complete their outer shell. So, an atom that has 2 outer electrons will often form a chemical bond with an atom that lacks two electrons to be complete. For example, a sodium atom has one lone electron in its outer shell.
Actually the bond would be an ionic bond because the chemicals are on either side of the periodic table. The chemicals wouldn't share the valence electrons, the chemical of calcium would give up it' selectron because it takes less energy. Actually the bond would be an ionic bond because the chemicals are on either side of the periodic table.
