Two Methods in Naming Transition Metals
Stock Method Classic Method
Uses Roman Numerals with Lower charge ends with –ous
Parenthesis Higher chrge ends with –ic
• The name of metals does not change
Ex. Rules of
Calcium (Ca) -> Calcium (Ca+)
Lithium (Li) -> (Li+) Naming
• The name of nonmetals change Ions
Root of element + -ide = name of ions
Ex.
Chlorine (Cl) + electron = Chloride
Bromine (Br) + 2 electrons = Bromide
-it e
-ate Polyatomic Ions
Are group of atoms that behave as unit -ite
and for less oxygen
carry a charge -ate for more oxygen
Chemical
Formula
The shorthand method
used to show the number
of atoms
Crisscross Method
A method wherein the
numerical charge of ion is
crossed over and used as the
subscript of the other ion.
Binary Covalent Compound
Steps in naming Binary
Sharing of electrons between two
Covalent Compunds
different nonmetals Step 1: write the name of the first
nonmetal
Step 2: Write the name of second metal
changing its ending to –ide
Step 3: Add prefixes to specify how
many of each element are present
Covalent
Compounds!
● Compounds that are formed through the covalent
compounds
• Compounds of
hydrogen, oxygen, and
usually nonmetals
• Uses –ous for lower
oxidation state
• Uses –ic for higher
oxidation state
