Title: Naming Compounds in Which Covalent Bonding Occurs
1Naming Compounds in Which Covalent Bonding Occurs
a) Naming Binary Molecular Compounds
b) Naming Compounds that contain Polyatomic Ions.
Naming Binary Molecular Compounds
- If two non-metals form only one compound, the
compound is named according - to this pattern
(name of the more electropositive atom)
(start of name of more electro Negative atom
ide )
2If a pair of elements forms more than one
molecular compound
The prefix for one (mono-) generally is omitted
when it would modify the name of the more
electropositive element.
3Naming Compounds that Contain Polyatomic Ions
Name the following ionic compounds that contain
polyatomic ions

5Elements Forming More than One Ion
The transition elements and the metal found late
in Groups III, IV, and V differ from the Groups I
and II metals in that they often form more than
one stable ion in compounds and in solution.

When you heat it, it drives off the water, and
you get the anhydrous compound

(DOES NOT HAVE TO BE AN ION!!!
COMPOSITE ION OR MOLECULE
Why the charge?
- The total number of METAL-LIGAND bonds in a
complex (usually two to six) - is the
COORDINATION NUMBER
B) The
donor or ligating atom
is the atom of a ligand molecule that
actually provides the electron density to a
central atom

C)
Indicate the chemical formulas of coordination
complexes. The metal or central atom comes first.

BIDENTATE LIGANDS. Form two bonds to the central
atom.
