WebAug 19, 2024 · There are about twenty elements that exist in only one isotopic form (sodium and fluorine are examples of these). An important series of isotopes is found with hydrogen atoms. Most hydrogen atoms have a nucleus with only a single proton. About 1 in 10,000 hydrogen nuclei, however, also has a neutron; this particular isotope is called deuterium.
WebThe identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes. Number of electrons can be altered to create ions.
