Atomic Mass

Subject: Chemistry

Book: General Chemistry

Atomic mass refers to the weighted average mass of an element’s isotopes, measured in atomic mass units (amu). For instance, chlorine has two major isotopes, and its average atomic mass reflects their relative abundances. The mass number (A) is a related concept, representing the total number of protons and neutrons in a single isotope. Understanding atomic mass helps scientists calculate molar masses and perform quantitative chemical reactions.
