The prime energy producer in the sun is the fusion of hydrogen to form helium which occurs at a solar core temperature of 14 million kelvin. The fusion of nuclei in a star starting from its initial hydrogen and helium abundance provides that energy and synthesizes new nuclei as a byproduct of that fusion process. There are actually electrons neutrinos and photons involved that make the fusion of hydrogen into helium possible.
This is the simple version of the story. In the basic hydrogen fusion cycle four hydrogen nuclei protons come together to make a helium nucleus. The sun 10 7 k core hydrogen fuses to form helium through a process known as the proton proton chain often shortened to the.
Stars begin as a cloud of mostly hydrogen with about 25 helium and heavier elements in smaller quantities. Fusion powers the stars and high yield thermonuclear weapons. Energy is released in the process.
Fuse together under high temperatures and pressure to form a nucleus of helium. Fusion reactions occur naturally in stars like our sun where two hydrogen nuclei. This reaction produces about 3 6 10 11 kj of energy per mole of ce 4 2he produced.
This lost mass is converted into thermal energy during the fusion via einstein s e mc 2 equation. A helium nucleus has a mass that is 0 7 less than that of four hydrogen nuclei. The vast energy potential of nuclear fusion was first exploited in thermonuclear.
In cases where the interacting nuclei belong to elements with low atomic numbers e g hydrogen atomic number 1 or its isotopes deuterium and tritium substantial amounts of energy are released. Nuclear fusion process by which nuclear reactions between light elements form heavier elements up to iron. The nuclear fusion process in stars was discovered and anticipated by arthur eddington around 1920.
In this process different chain reactions are involved based on the mass of the star.
Nuclear fusion equation hydrogen to helium. The sun is a main sequence star and as such generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core the sun fuses 620 million metric tons of hydrogen and makes 606 million metric tons of helium each second. The fusion of lighter elements in stars releases energy and the mass that always accompanies it. Fusion reactions occur in stars where two hydrogen nuclei fuse together under high temperatures and pressure to form a nucleus of a helium isotope.
There are a number of different nuclear fusion. Fusion power works by colliding heavy hydrogen atoms to form helium releasing vast amounts of energy in the process as occurs naturally in the centre of stars. Nuclear fusion in a star in which abundant hydrogen is fused resulting in energy release and formation of helium.
