atomic number
atomic number often represented by the symbol Z, the number of protons in the nucleus of an atom , as well as the number of electrons in the neutral atom. Atoms with the same atomic number make up a chemical element . Atomic numbers were first assigned to the elements c.1913 by H. G. J. Mos... Read more
atomic mass
atomic mass the mass of a single atom , usually expressed in atomic mass units (amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass is always very close to the mass number (t... Read more
atomic weight
atomic weight mean (weighted average) of the masses of all the naturally occurring isotopes of a chemical element , as contrasted with atomic mass , which is the mass of any individual isotope. Although the first atomic weights were calculated at the beginning of the 19th cent., it was not unti... Read more

atomic bomb
atomic bomb or A-bomb, weapon deriving its explosive force from the release of atomic energy through the fission (splitting) of heavy nuclei (see nuclear energy ). The first atomic bomb was produced at the Los Alamos, N.Mex., laboratory and successfully tested on July 16, 1945. This was the cu... Read more
