How do atoms bond to form molecules? We use common table salt to show what happens between the electrons and nuclei in atoms of sodium and atoms of chlorine to bond them together into crystals of sodium chloride (NaCl).
Nice video which simply explains the basics of electrons, protons, positive & negative charges. The speaker adds some mnemonic devices to help us remember the facts and vocab. A quiz highlight the most important points, too. Probably would require a couple of viewings to remember all of the facts. Flipped classroom idea?
