Front

What are subscripts in a chemical formula?

Back

Numbers that indicate the number of each type of atom in a molecule.

Front

What are covalent compounds?

Back

Compounds formed by the sharing of electrons between atoms, typically having low melting and boiling points.

Front

What is malleability?

Back

The ability of a material to be hammered or pressed into thin sheets.

Front

What is ductility?

Back

The ability of a material to be stretched into a wire.

Front

What is the difference between a mixture and a compound?

Back

A mixture is a combination of two or more substances that retain their individual properties, while a compound is a substance formed when two or more elements chemically bond.

Front

What is an element?

Back

A pure substance that cannot be broken down into simpler substances by chemical means.

Front

What are ionic compounds?

Back

Compounds formed by the transfer of electrons from one atom to another, typically having high melting and boiling points.
