    • polar covalent bonds

  • weak chemical bonds

  • hydrogen bonds

Atoms & Molecules - Ionic bonds are attractions between ions of opposite charge

  • electron transfer between 2 atoms moves 1 unit of negative charge from one atom to other

    • original atom now has +1

  • recipient atom now has charge of -1

Atoms & Molecules - Ionic bonds are attractions between ions of opposite charge

  • ions

    • atoms in which number of electrons does not equal number of protons

      • carry a net electrical charge (+ or - )

    • types of ions

      • cations

      • anions

75

Atoms & Molecules - Ionic bonds are attractions between ions of opposite charge

  • cation

  • atom with net positive charge (+)

  • example:

    • sodium (Na) atom losses an electron, becomes sodium ion, or cation (Na+), with charge of +1

Atoms & Molecules - Ionic bonds are attractions between ions of opposite charge

  • Anion

  • atom with net negative charge (-)

  • example

    • chlorine (Cl) atom, gains one electron, becomes chlorine ion, or anion (Cl-), with charge of -1
