![]() (it's not quite that simple, otherwise we might find a way to fuse two lighter-than-iron nuclei to release energy and create a heavier-than-iron nucleus which we then split again back to the two original nuclei and release even more energy. a higher atomic number) than iron, fusion absorbs energy, and fission releases energy. Whereas, for elements with a higher proton count (i.e. a lower atomic number) than iron, fusion releases energy, but fission absorbs energy. Ron's given you the classic examples for fission and for fusion.Įither process can absorb energy, or release it.įor elements with a lower proton count (i.e. Q2 What is nuclear fusion It is the process in which two or more light nuclei collide with each other to form a heavier nucleus. "Confusion" comes from the same root word, and happens when you mix things up together in your mind - the "fusion" in "confusion" is the bringing things together.įission is a decrease in the number of protons by splitting the nucleus: "fission" means a split. Q1 What is nuclear fission It is the process in which the nucleus of an atom splits into lighter nuclei through a nuclear reaction. You know fusing means joining together, right? So that can help you remember which is which. In summary, nuclear fission and nuclear fusion are distinct nuclear reactions with different properties and applications.Fusion is an increase in the number of protons in the nucleus by fusing two nuclei. Applications: Nuclear fusion has the potential to be a near-limitless, clean energy source, but practical applications are still under development.Minimal waste: Fusion produces minimal radioactive waste, as the primary byproduct is helium, an inert gas.No chain reaction: Fusion reactions do not create a chain reaction, as the process is self-limiting.Energy release: A tremendous amount of energy is released in the form of light, heat, and charged particles.Light elements: Fusion primarily occurs in light elements with small nuclei.This reaction typically involves light elements, such as hydrogen, and occurs under extremely high temperatures and pressures, like those found in the core of stars. Nuclear fusion is the process by which two or more atomic nuclei combine to form a single, more massive nucleus, releasing a large amount of energy. Applications: Nuclear fission is used in nuclear power plants to produce electricity and in nuclear weapons.Waste products: Fission produces radioactive waste, which requires long-term storage and management.Chain reaction: Fission reactions can create a chain reaction, as the released neutrons go on to cause further fissions.Energy release: A significant amount of energy is released in the form of kinetic energy and gamma radiation.Heavy elements: Fission primarily occurs in heavy elements with large nuclei.This reaction typically involves heavy elements, such as uranium or plutonium, which are induced to fission by capturing a neutron. Nuclear fission is the process by which an atomic nucleus splits into two or more smaller nuclei, releasing a substantial amount of energy. This article will explore the differences between these two phenomena. Two of the most widely known nuclear reactions are nuclear fission and nuclear fusion. ![]() Nuclear reactions are processes that alter the structure of atomic nuclei, resulting in the release or absorption of energy.
