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.
