atomic weight
Množina: atomic weights
Or atomic mass; The mass of an atom. It depends on the number of protons and neutrons in the atom, the electrons having negligible mass. It is calculated relative to one-twelfth the mass of an atom of carbon-12. If more than one isotope of the element is present, the atomic weight is calculated by taking an average that takes account of the relative proportions of each isotope, resulting in values that are not whole numbers.
(Chemistry) The ratio of the atomic mass of an element to half the atomic mass of carbon-12; SYN. relative atomic mass.
