The atomic mass of an atom is the sum of the number of protons and neutrons in the nucleus. It is generally expressed in atomic mass units (amu). The atomic mass is important for determining the overall mass of an atom and for calculating molar masses in chemical reactions.
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number)
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Atomic mass is the mass of an atom, typically expressed in atomic mass units (amu). It is a weighted average of the mass of an atom's isotopes, taking into account their relative abundance in nature. It is usually found on the periodic table beneath the chemical symbol of each element.

The atomic mass of an element is the weight of the constituent atomic paraticles in an atom of a given isotope. The atomic weight is the weighted average mass for atoms in a naturally occurring sample of the element.Almost all of an atom's mass is found in the nucleus, consisting of protons and neutrons.
The atomic number of an element represents the number of protons in its nucleus, which determines its position on the periodic table and its chemical properties. The atomic mass (or atomic weight) of an element reflects the average mass of its isotopes, considering both protons and neutrons. In general, the atomic number is a whole number without units, while atomic mass is usually expressed in atomic mass units (amu).
