The element is hydrogen. The easiest reaction to produce on earth (though still very difficult) is between deuterium and tritium. Deuterium is hydrogen with one proton and one neutron, tritium has one proton and two neutrons. Deuterium (heavy water) can be separated from ordinary water whilst tritium has to be made from lithium in a nuclear reactor, and it is radioactive with a half life of 12 years so it does not occur in nature.
They are related because it is the element most often used in fusion in both the natural and synthesised fusions of the universe. Look up fusion in the sun for more information
Nuclear fusion is used only in experimental installations.
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
Fission. Fusion has never been used on Earth, except for nuclear weapon tests.
Nuclear reactions may or may not involve nuclear transmutation. We need to split hairs here to arrive at the correct answer, and the answer involves the definition of the word transmutation. We sometimes think of transmutation as the changing of one element to another. Fission and fusion reactions do this, and many kinds of radioactive decay also convert one element into another. But there are some kinds of nuclear reactions that do not change an atom from one element to another, but instead change it from one isotope of a given element into another isotope of that element. There are a number of examples of this, and one is where isotopes of a given element absorb a neutron and become another isotope of that element. A given nucleus incorporates the neutron into its nuclear arrangement and the next heavier isotope of that element is created. If a "strict" definition of transmutation is used where it means a nuclear reaction that changes one element into another, then no, this does not always happen as illustrated above with the example of neutron absorption. If a more general interpretation of the term is used where we say that the nucleus transmutes meaning changes configuration, then yes, nuclear reactions involve nuclear transmutation.

A nuclear energy plant produces electricity by either nuclear fusion or fission. Fusion is the combining of two atoms of the same element (such as hydrogen) to produce a new element (helium). Fission is the process of breaking down a large unstable atom of one element into two different elements. Both fusion and fission produce enormous amounts of energy and heat. The heat produced is used to heat water into steam which is then used to rotate the blades of a turbine which produces electricity.
Nuclear energy can be converted into other forms of energy through processes such as nuclear fission or nuclear fusion. In nuclear fission, the energy released from splitting atoms is used to generate heat, which can then be converted to electricity through turbines. In nuclear fusion, the energy released from combining atoms is harnessed in a similar way.
Nuclear fusion is not used for any purpose at present, it is still in the experimental phase
Nuclear fusion is used only in experimental installations.
Nuclear fusion.
A nuclear weapon requires enriched uranium or plutonium as the fissile material to sustain a chain reaction and create a nuclear explosion. Additionally, a conventional chemical explosive is needed to trigger the nuclear reaction.
Nuclear bombs use nuclear fission of some heavy element, usually uranium or plutonium. Thermonuclear bombs use the detonation of a fission bomb to ignite the fusion of hydrogen. Such weapons are more powerful than ordinary nuclear weapons because nuclear fusion releases more energy than nuclear fission, and because the process of fusion itself can be used to ignite more fission.
Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system. There is a link below to an article on nuclear fusion.
Both are used.
