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.
The number of protons, neutrons and electrons.
The number of protons and neutrons.
atomic number
atomic mass
The atomic mass is determined by the neutrons and the protons, found in the elements' nucleus.
The atomic mass is mainly determined by the total number of protons AND neutrons.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.

a neutron determines the atomic mass
atomic mass
The atomic mass is determined by the neutrons and the protons, found in the elements' nucleus.
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
The atomic mass number is the sum of the protons and neutrons in an atom.
No. The element's atomic number determines how it forms compounds.
they determine the atomic mass of the atom
The atomic mass is mainly determined by the total number of protons AND neutrons.
protons plus neutrons
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The Atomic Mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
