Radioactivity
... Radioactive decay is a random process. If you look at a nucleus, it might decay within ten seconds, or twenty two million years. Since there are many billions of nuclei, a random decay pattern is seen. What is half-life? Radioactive substances will give out radiation all the time, regardless of what ...

Protons are the identity of an atom!
... Neutrons have neutral (sometimes stated as a neutral or zero (Ø) charge), and each has a mass of 1 amu. Electrons have a negative (-) charge, and a very tiny mass of 0.005 amu. The mass of electrons are so small that they are ignored when adding up the mass of the entire atom to state the atom’s ato ...
