I)
Molecules
A molecule is the smallest electrically neutral unit of a substance that still has the
properties of the substance. A molecule is made up of 2 or more atoms.
Define and give an example of:
II)

Monatomic-

Diatomic molecule-

Triatomic molecule-
Ions
Atoms are electrically neutral; however, ions are atoms or group of atoms that have a
positive or negative charge.
A ____________ is any atom or group of atoms that have a positive charge.
A ____________ is any atom or group of atoms that have a negative charge.
Do the metallic elements form cations or anions?
Do the non-metallic elements form cations or anions?
III)
Ionic Compounds
**Ions are not electrically neutral, but ionic compounds are**
What is an ionic compound composed of?
Binary ionic compounds name  formula (criss-cross method):
a) lithium fluoride
b) barium nitride
c) magnesium oxide
Notes Continued:
Binary ionic compounds formula  name:
a) NaCl
b) K2S
c) SrO
Many of the transition metals have more than one common ionic charge so the Stock
system is used. The Stock system includes a roman numeral after the element’s
name/symbol to indicate the numerical value of charge.
Stock system for binary ionic compounds name  formula (criss-cross method):
a) Iron (II) oxide
b) Iron (III) oxide
c) Cobalt (II) nitride
Stock system for binary ionic compounds formula  name (reverse criss-cross):
a) V2O5
b) CuO
c) MnO2
Polyatomic ions are tightly bound groups of atoms that behave as a unit and carry a
charge.
Polyatomic ions in an ionic compound name  formula (criss-cross method):
a) sodium hydroxide
b) iron (II) nitrate
c) ammonium sulfate
Polyatomic ions in an ionic compound formula  name:
a) Ca3(PO4)2
b) PbCO3
c) Cr(ClO)3
