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.
When two hydrogen atoms come close enough to each other, their electrons are attracted to the proton of the other atom. Because there is both a strong enough attraction betweeen atoms and room for electrons in the outer energy level of both atoms, the atoms share electrons. This forms a covalent bond. Tell students that there are two main reasons why two hydrogen atoms bond together to make one hydrogen molecule:
