the process by which multiple like-charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy, which allows matter to enter a plasma state.
The mass that is lost during nuclear fusion is converted into energy according to Einstein's equation, E=mc^2. This released energy is what powers the sun and other stars.
Ionising radiation was discovered in Würzburg in Germany by Wilhelm Rontgen in 1885. This discovery led to nuclear power.
Nuclear fusion. Stellar fusion in volves a number of different fusion reactions throughout the star's life, but the primary and (usually) the longest burning is the fusion of hydrogen into helium. This consumes most of the nuclear energy in the sun, and it usually accounts for the type of fusion that goes on for most of the life of the star. A link is provided to the Wikipedia article on the proton-proton chain, which is the "technical term" for hydrogen fusion into helium.
Nuclear power was invented to generate electricity by utilizing the heat produced from nuclear reactions. It was developed as a way to provide a reliable and efficient source of energy to meet the increasing demand for electricity globally. Additionally, nuclear power was seen as a way to reduce reliance on fossil fuels and mitigate greenhouse gas emissions.
By fusing hydrogen or hydrogen isotopes (deuterium and tritium) into helium. The result requires less residual binding energy1 than the original components due to the mass deficit curve. The excess residual binding energy is released, mostly in the form of heat and other energetic particles. -------------------------------------------------------------------- 1Binding energy holds quarks together to form protons and neutrons. Residual binding energy, also know as nuclear force, holds protons and neutrons together to form the nucleus.
Nuclear fussion
Fussion
Both release excess nuclear binding energy.
The cores of stars and hydrogen bombs.
no, but the products of fission are radioactive
There is a lower risk of runaway chain reactions.
Nuclear fussion of Hydrogen to give helium, positron and energy
Very carefully

Only at the core where the temperature and pressure is high enough.
Light elements combined to form the heavier elements.
If you're referring to nuclear energy in power generating plants, it is nuclear fission. If you're referring to the nuclear energy in our Sun, it is nuclear fusion.
