The two words are synonymous, so if you're looking for the number of atoms in an element, the answer is always one, and only one. Scientists know of 118 different elements, which they categorize in the periodic table, a diagram that arranges them in increasing order according to the number of protons in their nuclei.

Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons.
