Lewis Dot Structures of Covalent Compounds

Lewis Dot Structures of Covalent Compounds. Atoms are made up of protons, neutrons, and electrons. The protons and neutrons are located at the center of the atom, the nucleus. These electrons can be divided into core electrons and valence electrons. The valence electrons are
