CHM1045 Chemical Nomenclature Flashcards

Chemical Nomenclature of Ionic Compounds:

Name the cation first, and then the anion.

Monoatomic cation:

Given name of element.

Monoatomic anion:

Given name of element + suffix "ide."

Polyatomic ion:

Given name of ion.

What are variable charge metals?

Metal elements that form cations of differing magnitudes (charge numbers).

Chemical Nomenclature of Compounds With Variable-Charge Metals:

1. Name the cation first, and then the anion.

2. Specify the charge of the metal ion by a Roman numeral after its name.

What is a hydrate?

A compound (often ionic) with bound water molecules within.

Chemical Nomenclature of Hydrates:

1. Name the anhydrous compound with the cation first, and then the anion.

2. Add the word hydrate with a Greek prefix denoting the number of water molecules.

Naming Binary Molecular (Covalent) Compounds:

1. Name the more metallic element (furthest left/bottom) first, and the more nonmetallic element (furthest right/top) + suffix "ide" after.

2. Designate the number of atoms of each element with Greek prefixes.

Naming Acids:

1. Change hydrogen to the prefix "hydro."

2. Change the other nonmetallic element name by adding the suffix "ic."

3. Add the word "acid" as a second word.
