## Roman Numerals with Prefixes | Roman Numeral | Arabic Number | Prefix | |---|---|---| | I | 1 | Mono | | II | 2 | Di | | III | 3 | Tri | | IV | 4 | Tetra | | V | 5 | Penta | | VI | 6 | Hexa | | VII | 7 | Hepta | | VIII | 8 | Octa | | IX | 9 | Nona | | X | 10 | Deca | ## Binary and Transitions - **Criss Cross Method for Elements**: - Example: `FeBr2` (Iron (II) Bromide) - **Answer**: `A12 (SO4) 3` - The criss cross method assigns charges to the ions in a compound based on their position in the periodic table. - **Binary Transitions**: - **Ferric Bromide**: - The higher transition refers to "ferric" - Iron (III) - with a +3 charge. - Its formula is `FeBr3` - **Tin (II) Fluoride** - The lower transition refers to "tin (II)" with a +2 charge - Its formula is `SnF2` - **Answer**: `TaSn` ## Naming Acids **Add** | **Add** | **Add** | **Add** | |---|---|---|---| | **-ic** | **-ous** | **-hydro-t-ic** | **-ate** | | **-ide** | **-ite** | **-ide** | **-ite** | - **Example**: - `H2SO4` = **Sulfuric Acid** - The `ate` ending implies the acid is derived from the **sulfate** ion, which is the polyatomic ion `SO4` with a charge of -2. - **Example**: - `H2S` = **Hydrosulfuric Acid** - The `ide ending implies the acid is derived from the **sulfide** ion, which is the polyatomic ion `S` with a charge of -2. - **Note**: - The word *hydrosulfuric* means "sulfide". This name is only given to binary acids, which consist of hydrogen plus a non-metal, like hydrogen sulfide. - **because of ide**
