They are made up of even smaller [[subatomic particle]]s like the [[proton]]s, [[neutron]]s, and [[electron]]s. Protons and neutrons, held by the [[nuclear force]] is what makes up the positively charged [[atomic nucleus]] in the center. The negatively charged electrons exist around the nucleus in different energy states called as [[orbital]]s, defined by the [[electromagnetic]] force between the nucleus, which is governed by the [[uncertainty principle]]. The unique chemical property of all the atoms in the universe arises from the [[atomic number|number of protons]] found in the nucleus, which makes up most of the [[atomic mass]]. |
