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.
This forms a covalent bond. Tell students that there are two main reasons why two hydrogen atoms bond together to make one hydrogen molecule: There needs to be a strong enough attraction between the electrons of each atom for the protons of the other atom. There needs to be room in the outer energy level of both atoms.
