What are the rules for naming chemical compounds?
Rules for naming simple ionic compounds.
- Name the metal by its elemental name.
- Name the nonmetal by its elemental name and an -ide ending.
- Name metals that can have different oxidation states using roman numerals to indicate positive charge. Example Fe2+ is Iron(II)
- Name polyatomic ions by their names.
Does chemistry require memorization?
yes it is mostly memorization at A level. If you carry on with physics at uni you’ll find that you learn how to explain/understand quite a few things that just have to be limited to memorization in A-level chemistry.
What are the nomenclature rules?
Chemists use nomenclature rules to clearly name compounds. Ionic and molecular compounds are named using somewhat-different methods. Binary ionic compounds typically consist of a metal and a nonmetal. The name of the metal is written first, followed by the name of the nonmetal with its ending changed to –ide.
