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.
Molecules and Compounds. When atoms come together to form ionic or covalent bonds, they form stable associations that change the properties of either atom alone. These new molecules exhibit unique emergent properties. A molecule exists when two or more atoms join together by forming chemical bonds. A single molecule can be as small as only two atoms, like the oxygen we breathe, or as large as 5 sextillion (5 with 21 zeroes after it!) carbon atoms, like a 1â2 carat diamond in an engagement ring.
