Those who understand electrical theory might notice that positively charged particles packed closely together would repel one another. The nucleus stays together because of what is known as the ''strong nuclear force''. The quantization of this force is a tiny particle called a "gluon".

Chemical elements are made up of atoms with certain properties. The number of protons in the nucleus of an atom (known as the [[atomic number]]) determine the properties of the atom, and the element it constitutes. For example, [[Hydrogen]] has one proton, and therefore an atomic number of 1. [[Oxygen]] has 8 protons in its nucleus and has an atomic number of 8. Under normal conditions, atoms contain an equal number of protons and electrons.
