WebDec 26, 2014 · The atomic number is the number of protons in an atom of an element. for example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus. The interesting thing here is that every atom of krypton contains 36 protons. If an atom doesn't have 36 protons, it can't be an atom of krypton. dauphin county home rehab programWebOct 7, 2015 · 18. Your chemistry teacher is wrong. On the other hand, protium is the only stable element with no neutrons but this is more to do with the fact that there are no protons repelling each other in the nucleus, rather than stopping the electrons crashing into the nucleus. That problem is solved by recognising that electrons' energies are quantised. black air force 1 designWebThe number of protons is the key to which element the atom is. 6 protons in the nucleus is a carbon atom. 26 protons is an iron atom.
