An isotope is named after the element and the mass number of its atoms. 1800's, this particular problem has not yet been solved analytically, and so numerical methods - which are approximate at best, in this case - must be used. Radioactive isotopes are called radionuclides. As you see all the isotopes have the same number of protons (atomic number), therefore they also have the same number of electrons. 6 keV, the maximum at 18. However, we will discuss the lone atoms, which exist in three varieties: protium, deuterium, and tritium. The single thing that makes each element unique is the number of protons in its nucleus. Hydrogen is the lightest chemical element with its most common isotope consisting of just a single proton and electron. Deuterium and tritium fuse to form helium plus a free neutron, then releasing huge amounts of energy (1. It is radioactive, with a half-life of about 10 years.
