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.
Carbon is the main constituent of all living cells. It has chemical properties that make it the most important biological element. For instance, it forms strong chemical bonds and can form single bonds with up to four other atoms. It can bond to itself. It can also form double and triple bonds. Carbon is one of the only elements, because of its bonding properties, that can create long chain-shaped molecules or ring shaped molecules.
