Enter the number of protons (Z) and neutrons (N) to calculate the atomic mass
The atomic mass calculator determines the atomic mass along with its unit and symbol. For a given element, it is the quickest and easy way to find the combined mass of proton, electron, and neutron in an atom.
Atomic mass accounts for the overall mass of an atom, considering its protons, neutrons, and electrons. It is expressed in the atomic mass unit (amu) and expressed by the symbol "U".
However, the electron is 1,836 times lighter than a proton therefore, their contribution to the overall mass of most atoms is minimal.
Atomic mass is expressed in atomic mass units (u), also known as Daltons (Da). An atomic mass unit (Dalton) is 1/12 of the mass of a carbon atom. Therefore, the unit of atomic mass is \( 1.66 \times 10^-27 kg \).
Atomic mass (u) = number of neutrons + number of protons
OR
\(\ A = N + Z\)
Where:
As we know the atom has a neutral charge and it require neutrons for some reason: to add mass to the nucleus and stabilize it against the repulsive force between positively charged protons. The atomic mass calculator makes their determinations easy.
However, all the positive charges are concentrated in the center of the proton. Just as charges repel, there is a force that tries to destroy the core or nucleus of an atom. The opposite of this force is the strong nuclear force that exists between neutrons and protons.
Therefore, the total amount of strong nuclear attraction can be increased by adding neutrons to prevent atomic destruction. However, the Mole Calculator helps you to calculate the number of moles of a substance based on the molecular weight and the quantity of that material.
