Types of bonds

Types of Bonds

page 109


Na

Ions

  • an atom or molecule that is positively or negatively charged

  • number of protons and electrons are NOT equal

  • oppositely charged ions are attracted to each other

Na+


Ionic Bonds

  • to “fill” their outer energy shell, atoms give or “steal” electrons from each other

  • this transfer of electrons creates oppositely charged ions.

  • oppositely charged ions are attracted to each other, so they bond with each other


Covalent Bonds

  • to “fill” their outer energy shell, “share” electrons with each other


Molecules

  • result from ionic and covalent bonds

  • a group of two or more atoms held together by chemical bonds

  • make up compounds- a combination of two or more elements
