Chemical Bonds Part 3

bond formed by the sharing of electrons COVALENT BOND bond formed by the sharing of electrons

Happens when Two non-metals are joined together When the atoms share electron pairs Octet rule is still in place Examples; O2, CO2, C2H6, H2O, SiC

Covalent bonds Oxygen Molecule (O2) Atoms share electrons to fill outer shells Oxygen Atom Oxygen Atom Oxygen Molecule (O2)

Watch it Happen Covalent Bonds

Diatomic Elements Some atoms cannot be alone They must be combined with something so are often paired with another of the same: H O F Br I N Cl H2 O2 F2 Br2 I2 N2 Cl2 These are always covalent

Naming Covalent Compounds See the handout that Ms. D has for you. You can put this straight into your notebook as the notes.
