5a. Ions are particles when a metal and non-metal elements get close to each other (formed an "ionic bond or compound", transferring valence electrons between them). Actually just a known set of ions (positive and negative ions) that are being held together via Coulombic force.<br> 5b) Molecules are particles when two or more non-metal elements get close to each other (formed a covalent bond where valence electrons are shared between two non-metals).<br> <br> 5c) In a metal, the metallic bond is created from metal elements losing their valence electrons to form cation ions (positively charged atoms) and the "lost" electrons bounce between other metal atom (who also don't want the electrons) creating the "sea of free flowing valence electrons" that give metals it characteristics.<br>
