Does nuclear fusion require hydrogen?

First, fusion requires both extremely high temperatures to give hydrogen atoms enough energy to overcome repulsion between the protons. Second, high pressures are needed to squeeze hydrogen atoms close enough to fuse. This process is done by using intense magnetic fields, lasers, or ion beams.

Can carbon be used for fusion?

During helium fusion, stars build up an inert core rich in carbon and oxygen. However, the balance is only short-lived; in a star of 25 solar masses, the process will use up most of the carbon in the core in only 600 years. The duration of this process varies significantly depending on the mass of the star.

Does fusion mainly use hydrogen?

In the sun, the nuclear fusion process occurs mainly between hydrogen and helium, since that is the bulk of its composition. The sun’s fusion processes are on a scale so massive that it’s difficult to take it all in. In its core, the sun fuses over 600 million tons of hydrogen every second.

Does nuclear fission or fusion use hydrogen?

Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.

In what way are nuclear fission and nuclear fusion similar?

Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.

Is nuclear fusion possible?

Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur. The nuclei can then fuse, causing a release of energy.

In what way do nuclear fission and nuclear fusion differ?

Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
