    Atoms are represented using a notation that includes the chemical symbol, atomic number, and atomic mass. The chemical symbol is a one or two-letter abbreviation, atomic number indicates the number of protons, and atomic mass denotes the sum of protons and neutrons. For example, carbon is represented as “C-6.02 x 10^23” with 6 protons and an atomic mass of approximately 12.
