Difference between atomic mass and weight

WebJul 29, 2024 · As you learned, the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is an integer that is approximately equal to the numerical value of the atomic mass. Although the mass number is unitless, it is assigned units called atomic mass units (amu). WebNov 4, 2011 · • Atomic number of an element is the number of protons it has in the nucleus. Atomic weight is the average weight calculated considering all the masses of isotopes. • Number of protons and neutrons are largely contributing to the atomic weight. (This is because the mass of an electron is very small compared to a proton or a neutron).

This is known as the total isotopic mass. The atomic masses of elements change from 1.008 amu for hydrogen up to 250 amu for elements that have an extremely high atomic number. Atomic mass (ma) is the mass of an atom. A single atom has a set number of protons and neutrons, so the mass is unequivocal (won't change) and is the sum of the number of protonsand neutrons in the atom.
