Nomenclature Part 3: Polyatomic Ions
Ionic Compounds Containing Polyatomic Ions
Compounds containing more than two types of atoms are called polyatomic
compounds. They are formed by the combination of a single element ion and a
polyatomic ion (a
Nomenclature Part 5: Covalent Compounds
A non-metal element is bonded to another non-metal.
Properties of covalent compounds:
Low melting point
Do not conduct electricity
3. Low boiling point
Formation of covalent compounds: With c

Ca = _ atoms; N = _ atoms; O = _ atoms
2Ca(NO3)2 Ca = _ atoms; N = _ atoms; O = _ atoms
*the 2 in front of Ca(NO3)2 is called a coefficient: all of the subscripts in a formula
Nomenclature Part 1: Simple Binary Ionic Compounds
These are the simplest to name. The formulas will only have one type of atom in them.
Can be represented by the symbol for that element. Examples include: Fe, Ar, Na. You are
Nomenclature Part 2: Multivalent Metals
Ionic compounds with multivalent metals
Some of the transition metals have more than one possible valence. When naming
compounds containing a multivalent metal (also called variable valence) metal, you

Properties of Bases
Acids are aqueous compounds that
contain hydrogen. An acid will release
hydrogen ions, or protons [H]+ in solution.

Testing for Acids and Bases
Purpose: You and a partner will be responsible for testing the pH of household substances to see
whether it is acidic, basic, or neutral.
