Using a pre printed electron configuration of a sodium atom, showing the electron configuration of 2-8 and 1 electron in the last energy level, the increase in stability was indicated by removal of the single electron, leaving 8 in the new last energy level. The same was done with a pre printed atom of chlorine, showing 2-8-7 configuration. The gain of 1 electron to chlorine would stabilize the atom by now having electrons in the last energy level. That these are now ions was elicited. The sodium was a +1 ion and the chlorine a -1 ion. The attraction between unlike charges was recalled from earlier work, indicating that the sodium ion and chloride ion were now bonded together to form a compound, called sodium chloride. The recognition of NaCl as table salt was noted. A YouTube video showed the violent reaction of sodium and chlorine to form the salt. It was pointed out that both sodium and chlorine are toxic substances, but that the compound formed is eatable. The same was done for lithium and chlorine and sodium and fluorine.
