Compounds
Compounds are substances made up of more than one type of atom which has been chemically bonded and are now brand new products. When naming compounds, the easiest situation, and quite a common one, is when non-metals react with metals. You use the metal as the first word, and the non-metal as the last word, but you also add a specific ending. You add -ate if lots of oxygen has reacted with it. If not, then you will just add -ide. For example, imagine a copper and sulphur reaction. If the two elements reacted out in the open, the end product would be Copper Sulphate, but if the reaction happened in a boiling tube which was blocked by cotton wool, because you wanted to avoid inhaling the sulphur dioxide, then it would just be Copper Sulphide. When I say out in the open, I don't mean that the people are absurd enough to just be open too. Either the reaction could happen naturally or away from other things, or just carried out by people wearing safety equipment.
