Naming Ionic and Covalent Compounds

Front

What is an ionic compound?

Back

How do you name covalent compounds?

Back

Covalent compounds are named using prefixes to indicate the number of atoms of each element, followed by the name of the first element and the second element with an '-ide' ending.

What is the difference between a monatomic ion and a polyatomic ion?

Back

A monatomic ion consists of a single atom with a positive or negative charge, while a polyatomic ion consists of two or more atoms bonded together that carry a charge.

What is the naming convention for binary ionic compounds?

Back

Binary ionic compounds are named by combining the name of the metal cation with the name of the nonmetal anion, changing the anion's ending to '-ide'.
