Y8 ds insists that 'dioxide' is the proper name for O2. When I queried his use of ' dioxide' he looked up the meaning of 'ide' online and is now convinced that it means 'two atoms in a molecule'. I've tried to explain that the' ide' suffix refers to two elements in a molecule, not two molecules of the same element, but I'm merely boring old mother who doesn't know anything. (Erm, hello? A-level Chemistry, all be it a few decades ago.)
Can anyone explain it in language he will accept, or point to any links explaining it? All the sites I've found are too high-level for him, going into too much detail about valencies and when Latin is used or Greek is used, etc etc. Also no mention that it is not used for pure elements, but only for compounds.
BTW ds is autistic.
