The letter H is used to denote protium, which is the normal form of hydrogen. An element’s isotope is described as an atom with the same number of protons but a different number of neutrons. The basic hydrogen atom, protium, has a single proton surrounded by a single electron. Their chemical properties should be similar because the isotopes have the same atomic number and electronic configuration. They do, however, differ in terms of the number of neutrons. The outer shell of all three hydrogen isotopes has one electron while the nucleus has only one proton. Due to the enormous differences in mass, they have different physical properties. However, because of the varied bond disassociation enthalpies, they have distinct reaction rates. Isotopes have similar chemical properties because their electrical arrangement is the same. Only tritium, out of these three hydrogen isotopes, is radioactive in nature and generates low-energy β-particles. Protium is the most common form of hydrogen, with deuterium accounting for 0.0156% of all hydrogen on the planet’s surface. There are no neutrons in protium, while one neutron is present in deuterium and two neutrons are present in tritium. Protium atoms make up the majority of hydrogen found in nature. In nature, the relative abundances of three isotopes are 1: 1.56×10 -2: 1×10 -18, respectively. Protium, deuterium, and tritium are the three naturally occurring hydrogen isotopes.ĭue to the various numbers of neutrons in each isotope, the isotopes differ. Hydrogen has three isotopes, each with a mass number of 1, 2, or 3. Isotopes are distinct forms of the same element with different mass numbers but the same atomic number. Hydrogen atoms make up about 15% of all the atoms on the earth. It is tenth in the order of abundance in crystal rocks. It’s not found in our atmosphere because the earth’s gravitational pull isn’t strong enough to hold light hydrogen molecules. It makes up 15.4% of the earth’s crust and seas. Hydrogen is found in a variety of minerals, including coal, petroleum, oil, and natural gas. Hydrogen is found on Earth in a variety of forms, mostly in combination with oxygen in the form of water, and in combination with carbon, nitrogen, and halogens in the form of organic matter in plant and animal tissues, carbohydrates, proteins, and other substances.
