Pre-Knowledge: Chemistry and Physics Vocabulary Atomic Number
... The sum of the number of neutrons and protons in the nucleus of an atom. Nucleus The small “core” of the atom, where most of its mass and all of its positive charge is concentrated. Except for ordinary hydrogen (which has only a proton), atomic nuclei consist of protons and neutrons. For this reason ...

... Some isotopes of some elements are unstable, so their nuclei break down spontaneously and emit rays and particles called emissions. They are radioactive. This breakdown or RADIOACTIVE DECAY occurs without any need to be triggered off by something. There are 3 different kinds of emissions identified: ...

Chapter 4 The Liquid Drop Model
... Since different isotopes have different atomic mass numbers they will have different binding energies and some isotopes will be more stable than others. It turns out (and can be seen by looking for the most stable isotopes using the semi-empirical mass formula) that for the lighter nuclei the stable ...
