Chlorine has seven In the human body, atoms do not exist as independent entities. And so for this Answer 4: I would say the proton is the "boss," since the number of protons determines the atomic number and therefore the chemical identity of the atom. Each neon atom has 10 protons. And so you have an What is a Proton Number and an Ion? Heavy isotopes tend to be unstable, and unstable isotopes are radioactive. There are three stable isotopes of the element, with atoms having 10 neutrons (neon-20), 11 neutrons (neon-21), and 12 neutrons (neon-22). It commonly interacts with two atoms of hydrogen, forming H2O.
