1. Cation (positive ion)
2. Anion (negative ion)
Example:
* Sodium chloride: Sodium (Na+) is the cation, and chloride (Cl-) is the anion.
Note:
* If the cation has multiple possible charges, a Roman numeral is used in parentheses after the cation's name to indicate its charge. For example, iron(II) chloride indicates that the iron ion has a +2 charge.
* The name of the anion usually ends in "-ide" (e.g., chloride, bromide, oxide).
* Some polyatomic ions have specific names (e.g., sulfate, phosphate, nitrate).
Here are some more examples:
* Potassium bromide: Potassium (K+) is the cation, and bromide (Br-) is the anion.
* Copper(II) sulfate: Copper(II) (Cu2+) is the cation, and sulfate (SO42-) is the anion.
* Calcium hydroxide: Calcium (Ca2+) is the cation, and hydroxide (OH-) is the anion.
