What are nuclear reaction explain nuclear fission and nuclear fusion with example?

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.

What is the main difference between a fission & fusion reaction?

The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

How is nuclear fusion related to chemistry?

Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released.

Why energy is released in nuclear fusion?

In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy. DT fusion produces a neutron and a helium nucleus.

Does nuclear fusion or fission create the most energy?

Fission only produces more energy than it consumes in large nuclei (common examples are Uranium & Plutonium, which have around 240 nucleons (nucleon = proton or neutron)). Fusion only produces more energy than it consumes in small nuclei (in stars, Hydrogen & its isotopes fusing into Helium).

Is nuclear fusion more dangerous then nuclear fission?

Nuclear fusion is safer than nuclear fission. Whereas a fission reactor has about ten years worth of fuel in it, gradually growing more and more toxic over time. So the amount that can be released in a most catastrophic imaginable accident is huge. Secondly, the products of fusion are few and safe.

Does nuclear fusion release more energy than nuclear fission?

Energy Released. The energy released by fission is a million times greater than that released in chemical reactions, but lower than the energy released by nuclear fusion. The energy released by fusion is three to four times greater than the energy released by fission.

What are facts about nuclear fusion?

Nuclear Fusion Some typical fusion reactions. Naturally occurring fusion. Thermonuclear reactions. Artificial fusion reactions. The hydrogen bomb. Peaceful applications of nuclear fusion. Inertial confinement. D – D and D – T reactions. Hope for the future. Cold fusion.
