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
The atomic mass is mainly determined by the total number of protons AND neutrons.
Atomic mass represents the total mass of an atom, combining the mass of protons, neutrons, and electrons. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and element identity.
Atomic number refers to the number of protons in an atom's nucleus, which determines the element's identity. Atomic mass is the average mass of an atom of that element, taking into account the mass of protons, neutrons, and electrons. Atomic mass is measured in atomic mass units (amu).
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
a neutron determines the atomic mass
atomic mass
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.
The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number determines the atom's mass, while the atomic number determines the element's identity on the periodic table.

Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
Atomic mass refers to the total mass of an atom, including the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which determines its chemical properties and place on the periodic table.
The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of the number of protons and neutrons in the nucleus. Atomic number determines an element's identity, while atomic mass affects its atomic weight and isotopes.
