Deuterium is an isotope of what essential element?
Answer Hydrogen
Also known as hydrogen-2 or heavy hydrogen, deuterium has double the mass of hydrogen because it consists of one proton, one neutron, and one electron — meanwhile, hydrogen only has one proton and no neutrons. Deuterium is much rarer than hydrogen and naturally appears on Earth in very small quantities.
