Question

anonymous · Answer

Hello there, Michael :) 
Welcome to Openstudy!
Some examples of covalent bonds, could be Diamond, Graphite, Sand, or even carbon dioxide. 
Covalent Bonds contain a non-metal, non-metal bond. It involves sharing a pair of electrons between atoms in a molecule

I'd like to sort of correct strawberrysorbet ... metal-metal boding is covalent, using her examples, diamond and graphite are both carbon - carbon bonding (just with different structure and % carbon)
non-metal - non-metal  covalents would be like water (H2O) or Sulfuric acid (H2SO4)
metal - non-metal examples would be sand (SiO2) and ethanol (C2H6O)

one way to remember covalent bonds is the term valence 
coVALENT bonds = sharing of VALENCE electrons to complete the shells 
now this means you need to know what are valence electrons, and I would like for you to further read that it is so you can use the mnemonic device I suggested

@agreene Metal-metal bonding is $\sf metallic$ not covalent.. and ethanol is not a metal-non metal compound, sir.
