Definition. Number is a grammatical category of nouns, pronouns, and verb agreement that expresses count distinctions (such as one or more than one). The count distinctions typically, but not always, correspond to the actual count of the referents of the marked noun or pronoun.
Atomic Number (Z) The atomic number is the number of protons in the nucleus of an atom. It is listed on the periodic table for each element. No two elements have the same atomic number (or the same number of protons), so the atomic number identifies the element.
