Labels:text | screenshot | font | number OCR: DEUTERIUM DEUTERIUM IS A form of hydrogen, often known as "heavy hydrogen." It is the most concentrated source of energy known. Unlike normal hydrogen, its nucleus contains a neutron as well as a proton. When deuterium nuclei fuse to form helium nuclei, an enormous amount of energy is released - over 3 million times the energy released by burning an equivalent weight of coal.
