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 Atomic Mass of an atom is the total mass of its protons, neutrons, and electrons. It is usually measured in atomic mass units (u) or grams per mole (g/mol). The atomic mass can be found on the Periodic Table as the average atomic mass of an element.
The atomic mass of an atom is the sumnation of the atom's protons and neutrons.

Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
The diffirentiate of atomic mass and atomic number?
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Atomic number is the number of protons in the nucleus of an atom. Atomic mass is the sum of the number of protons and neutrons, while atomic number is the number of protons only.
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What is the difference between the atomic number and atomic mass?
The atomic number represents the number of protons in an atom's nucleus. It determines the element's identity. Atomic mass is the average mass of an atom of an element, taking into account its isotopes and their abundance. It is the sum of the protons and neutrons in the nucleus.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
Atomic mass is determined by the number of protons plus the number of?

What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
What are the differences between atomic number and atomic mass?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
The diffirentiate of atomic mass and atomic number?
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Atomic number is the number of protons in the nucleus of an atom. Atomic mass is the sum of the number of protons and neutrons, while atomic number is the number of protons only.
What is the difference between atomic number and atomic mass weight?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What is the difference between the atomic number and atomic mass?
The atomic number represents the number of protons in an atom's nucleus. It determines the element's identity. Atomic mass is the average mass of an atom of an element, taking into account its isotopes and their abundance. It is the sum of the protons and neutrons in the nucleus.
Is atomic number the same as mass number?
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
What is the difference between atomic mass and atomic number?
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.
