Here are two ways to model radioactive decay. Dice and Blocks Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance ...

Proton emission is a rare form of radioactive decay, in which the nucleus emits a proton to take a step towards stability,” ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great ...

Numerous developments of interest to biologists and to medical investigators will undoubtedly result from the fact that certain radioactive isotopes are now available in sufficient quantities for ...
