Different atoms are composed of different numbers of protons, neutrons, and electrons.
When two or more different atoms join together chemically to form a new material, this material is called a ____.
A compound.
____ is considered to be one of the most abundant mixtures.
Air
____ considered to be one of the most abundant compounds.
