Study Notes
Atoms and Ions
- Atoms can gain or lose electrons to form charged particles called ions
- Ions are formed due to an imbalance of protons and electrons, which are oppositely charged particles
Types of Ions
- Monatomic ions: formed when a single atom gains or loses electrons
- Polyatomic ions: formed when a group of atoms collectively develops a charge
- The prefix 'mono-' refers to one atom, and the prefix 'poly-' refers to many (two or more) atoms
- The number of atoms in a polyatomic ion is variable
