WebThese two forms of hydrogen are called isotopes. Isotopes of an element have the same atomic number, but a different mass number. Hydrogen is the only element that has different names for its isotopes. Hydrogen with one neutron is also called deuterium, and the symbol is D. Hydrogen with two neutrons is called tritium, and the symbol is T. WebMar 31, 2024 · Summary Each isotope of hydrogen is made up of only one proton, but these isotopes differ in the number of neutrons the atoms contain. The extra neutrons make the isotopes heavier: deuterium is twice as heavy as ordinary hydrogen (sometimes called protium), while tritium is three times as heavy.
