WebThe nucleus is made out of a glued-together arrangement of protons and neutrons, but there are multiple possible ways that these protons and neutrons can be arranged. Some of these arrangements have a lower total energy, and so a nucleus in which the protons are initially close together may shift to the lower energy configuration after some time. WebThe ________ of an atom is the sum of the protons and neutrons in the nucleus of that atom. We get this number by rounding the atomic mass. It must be a whole number with no decimals because we cannot have less than one subatomic particle. (for example we cannot have 1/2 or 3/10 of a proton!) isotope. ________ are atoms of the same element that ...

The nucleus of an atom consists of neutrons and protons, which in turn are the manifestation of more elementary particles, called quarks, that are held in association by the nuclear strong force in certain stable combinations of hadrons, called baryons. Meer weergeven The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the … Meer weergeven Nuclei are bound together by the residual strong force (nuclear force).
