The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. Thus, the number of positive charges present in the nucleus of an element is called the atomic number of that element. In other words, neutrons are the subatomic particle responsible for maintainingthe structural integrity of the nucleus. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoesradioactive decay. What does the number next to isotopes signify? This discrepancy can be explained by a subtle, but incredibly important, piece of information: The calculation performed inExample \(\PageIndex{1}\) was done forasingle atomof hydrogen. Numerous permanent and temporary particles exist in the atom. Let me ask you a question. An elemental ion has 34 protons, 36 electrons, and 44 neutrons.
