Naming Ionic and Covalent Compounds
I am confused on how you would write out this sort of formula
Sn3(PO4)2 ? I don't get what the bracets() are for and why there is a number outside of it. (NH4)2SO4? |

Because there's 2 of the thing inside the brackets.
The brackets normally signify a group of elements that are found together. They are normally strongly bound and can be treated as a single species. |
