What is the number of atomic mass?
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)
What is atomic mass of an atom?
It's the mass of the atom, usually specified in atomic mass units where one amu is 1/12th the mass of a carbon-12 atom.
What does the atomic mass of an atom represent?
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.
What is the atomic mass of an 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.
What does the atomic mass describe?
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.
What douse the atom mass measure?
Exactly the mass of an atom expressed in atomic units of mass (u).

Which is not a reason why the mass of the atom is expressed in atomic mass units rather than in grams?
Scientist could not agree on a standard.

What do you do with an atomic number and an atomic mass?
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
