Naming of Polyatomic and Monoatomic Ions NOTES:
I. Positive Ions = cations (usually single metals or a combination of nonmetals)
A. Simple cations (single element) = use the name of the element
1. Simple cation with one type of charge
Ex. Mg+2 = magnesium ion
List and name 5 positive ions with their charges:
Ion with
charge
Name
1.
2.
3.
4.
5.
2. Simple cation with 2 or more charges (usually Transition Elements)
a. older name – uses Latin name and -ous or -ic ending
Ex. Iron (old name Ferrum) can be Fe2+ or Fe3+
Fe2+ = ferrous
Fe3+ = ferric
List and name 5 positive ions with their charges:
Ion with
charge
1.
2.
3.
4.
5.
“Old” Name (ous/ic)
NAME: ___________________________
b. stock name (uses English name and Roman number)
Ex. Fe3+ = Iron (III)
Fe2+ = Iron (II)
List and give the stock name 5 positive ions with their charges:
Ion with
charge
Stock Name
1.
2.
3.
4.
5.
B. Polyatomic cations (several elements together) = special names
There are two we will use in this course:
Ammonium = NH4+ and hydronium = H3O+
II. Negative Ions = anions (usually nonmetals
A. Simple anions (single element) = use the name of the element with the
ending converted to “-ide”
3Ex. N = nitride
Write names for these negative ions:
Ion with (-)
charge
Name
1.
2.
3.
4.
5.
B. Polyatomic anions = use the special name or the name ending
with “-ite” or “-ate”
Ex. OH- = hydroxide
Cr2O72- = dichromate
A) Write the names of these ions
C2H3O2- = acetate
C2O4-2 = oxalate

Formula
C. Oxoanions = polyatomic ions of an element and oxygen, usually in several
multiples of Oxygen. May also have a hydrogen attached to it.
