Atomic Mass Table

The atomic mass table lists elements along with their atomic weights, which indicate the average mass of all their naturally occurring isotopes. This value is measured in atomic mass units (amu) and reflects the element’s average mass considering the different forms its atoms can have. For example, carbon’s atomic mass is about 12.01 amu, representing a mix of isotopes like carbon-12 and carbon-13. The table helps scientists understand element properties, compare similarities, and perform calculations in chemistry and physics involving atomic-scale objects.
