Compound Names and Formulas
Slide2Naming Ionic Compounds
The names of ionic compounds consists of the names of the ions that make up the compound.
Names of
cations
include the elements of which they are composed.
Names of anions are altered names of elements.
An ionic compound must have a total charge of 0.
Some
cation
names must show their charge.
Determine the charge of a transition metal
cation
.
Write formulas for ionic compounds using names.
Slide3How to Name Simple Ionic Compounds
Write down the formula of the ionic compound
Write the name of the metal, or the
cation
. This is the positively charged ion in the compound, and it is always written first in ionic compound formulas.
Write the name of the nonmetal, or the anion, with the "-ide" ending.
Combine the names.
Slide4How to Name Transition Metal Ionic Compounds
Write down the formula of the ionic compound
Write down the charge of the metal
Write down the name of the metal
Write down the name of the nonmetal.
Put the first name and second name together
Slide5Naming Covalent C
ompounds
For covalent compounds of 2 elements, numerical prefixes tell how many atoms of each element are in the molecule.
If there is only 1 atom of the first element, the element does not get a prefix.
Ex: N
2
O
4
Di
nitrogen
tetr
oxide

Slide7Empirical Formula
An empirical formula tells us the smallest whole-number ratio of atoms that are in a compound.
Different compounds can have the same empirical formula.
Molecular formulas are determined from empirical formulas.
Molecular formulas tell how many atoms are in one molecule of the compound.
Masses can be used to determine empirical formula
