Binary Molecular Date:

Covalent Bonding  A chemical bond formed by the sharing of a pair of electrons between atoms.  NO CHARGES!!!!!  Occurs ONLY between 2 nonmetals  Metalloids are treated as nonmetals

To Name Binary Molecular  Name the first nonmetal  Add a prefix ONLY if more than one  Name the second nonmetal  ALWAYS add a prefix – regardless of number  Change the ending to -ide

Prefixes  Mono1  Di2  Tri3  Tetra4  Penta5  Hexa6  Hepta7  Octa8  Nona9  Deca10

Random Rule  If there are two vowels in a row, drop the “a/o” from the prefix  Never drop an “i”

Practice  Carbon monoxide  Carbon dioxide  Carbon tetrachloride  SiF 4  SO 2  SO 3  CO  CO 2  CCl 4  Silicon tetrafluoride  Sulfur dioxide  Sulfur trioxide

Complete BM Worksheet  Work through the Binary Molecular side of worksheet.  On back, Mixed Naming:  Circle # in Blue if starts with metal or NH 4. Use ionic rules – just name!  Circle # in Red if starts with nonmetal or metalloid. Use BM rules – prefixes!!!  Practice, practice, practice.
