Naming Rules for Binary Compounds

Ionic Compounds

Binary ionic compounds contain a positive ion (cation) and a negative ion (anion). The cation is typically a metal and is always written first in both the formula and the name.

Basic Rules:

• The cation is always named first and the anion second
• A cation takes its name from the name of the element (e.g., K⁺ → potassium)
• An anion is named by taking the first part of the element name and adding -ide (e.g., Br⁻ → bromide)

Oxyanion Naming Conventions

For oxyanion series (polyatomic ions with varying numbers of oxygen atoms):

Type I Binary Ionic Compounds

Type I compounds contain a metal that forms only one type of cation (e.g., Na⁺, Ca²⁺).

Type II Binary Ionic Compounds

Type II compounds contain metals that can form more than one type of cation. The charge is specified using Roman numerals in parentheses.

Binary Covalent Compounds

Covalent compounds contain two nonmetals. Naming follows these rules:

• First element uses the full name
• Second element is named as an anion (with -ide suffix)
• Prefixes indicate atom count: mono- (1), di- (2), tri- (3), tetra- (4), penta- (5), hexa- (6), hepta- (7), octa- (8)
• The prefix mono- is never used for the first element
• When oxygen follows a vowel-ending prefix, the vowel is dropped (e.g., monoxide, tetroxide, pentoxide)
