Study Notes
Ion Basics
- An ion is an atom or group of atoms that carries a net charge due to the gain or loss of electrons.
- Ions are categorized based on their charge: cations (positive) and anions (negative).
Cation
- A cation is formed when a neutral atom loses one or more electrons, resulting in a positive charge.
Anion
- An anion is created when a neutral atom gains one or more electrons, resulting in a negative charge.
Monatomic and Polyatomic Ions
- Monatomic ions consist of a single atom that carries a charge.
- Polyatomic ions are composed of multiple atoms bonded together, which collectively carry a charge.
Octet Rule
- The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full valence shell, typically consisting of eight electrons.
