- A cation is an ion with a positive charge.
- Cations are formed when an atom loses one or more electrons.
- Examples include sodium (Na+), calcium (Ca2+), and potassium (K+).
- Monovalent Ion
- A monovalent ion has a charge of +1 or -1.
- Examples include hydrogen ion (H+) and fluoride ion (F-).
- Polyvalent Ion
- A polyvalent ion has a charge greater than +1 or -1.
- Examples include sulfate (SO42-) and phosphate (PO43-).
- Ions in Chemical Reactions
