Naming Compounds, cations and anions

Elements and symbols that you should know: Part 1 – The obvious ones: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],H He Li Be B C N O F Ne Mg Al Si P

Some more obvious ones: ,[object Object],[object Object],[object Object],18) Calcium 19) Zinc The less obvious ones: ,[object Object],[object Object],[object Object],[object Object],[object Object],6) Tin 7) Gold 8) Mercury 9) Lead S Cl Ar Ca Zn Na K Fe Cu Ag Sn Au Hg Pb

Polyatomic ions (-1 charge) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Polyatomic ions (-2 charge) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Polyatomic ions (-3 charge) ,[object Object],[object Object]

Rule 1– If two identical elements combine then the name doesn’t change ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],These elements always go around in pairs (diatomic molecules). For example, hydrogen looks like this:

Rule 2 – When two elements join and one is a halogen, oxygen or sulphur the name ends with ____ide e.g. Magnesium + oxygen magnesium oxide ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

[object Object],[object Object],[object Object],[object Object],Rule 3 – When three or more elements combine and two of them are hydrogen and oxygen the name ends with hydroxide e.g. Sodium + hydrogen + oxygen Sodium hydroxide

Rule 4 – When three or more elements combine and one of them is oxygen the ending is _____ate e.g. Copper + sulphur + oxygen Copper sulphate ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
