Study Notes
Ions
- Ions are atoms that have gained or lost electrons, resulting in a net electrical charge.
Gaining an Electron
- When an atom gains an electron, it becomes negatively charged.
- This is because the atom now has more electrons (negative charge) than protons (positive charge).
Cations
- Cations are positively charged ions.
- They have lost one or more electrons, resulting in a greater number of protons than electrons.
Anions
- Anions are negatively charged ions.
- They have gained one or more electrons, resulting in a greater number of electrons than protons.
