Two main reasons: 1. At the high school level, there isn't a lot of nuclear chemistry on the curriculum. 2. Nuclear reaction resources are kind of expensive, and can be a little dangerous. Nevertheless, in my HS chem class, we do a little bit of nuclear - I have a Geiger counter and several closed-source radionuclides.
We don't generally think of nuclear reactions creating new molecules. A nuclear reaction is a reaction involving the nucleus of an atom (in the case of fission) or atoms (in the case of fusion). The manipulation or creation of new molecules is usually left in the domain of the science of chemistry, and not nuclear physics.
Only in nuclear physics and nuclear chemistry laboratories, in USA or Russia.
A chemistry course will usually focus on the periodic table of elements and how they interact with the world around them. Experiments may be done to illustrate some of these reactions.
Protons and neutrons, collectively known as nucleons, are the particles responsible for nuclear reactions in the atom. The strong nuclear force binds these particles together in the nucleus, leading to nuclear reactions such as fission and fusion.
Nuclear reactions and chemical reactions both involve changes to atoms and their components, but they differ in the processes and energies involved. In both types of reactions, bonds are formed or broken, leading to the transformation of substances. Additionally, both reactions can release or absorb energy; however, nuclear reactions typically release much more energy due to changes in the nucleus, while chemical reactions usually involve electron interactions. Ultimately, both processes are fundamental to understanding matter and energy transformations in nature.
A power plant is an example of nuclear energy because it generates electricity through nuclear reactions, usually fission. The energy released from these reactions is harnessed to produce heat, which then drives turbines to generate electricity.
By 'normally,' we mean 'through chemical means.' Strictly speaking, the atom (the smallest single unit of an identifiable element) is the smallest piece of something that there can be, within the field of chemistry, that is. The word atom is derived from a greek word that means 'indivisible,' because it is usually just that, indivisible. Chemistry is largely a science of how atoms and the electrons orbiting atoms behave and interact. And that's why there is always this caveat; outside the field of chemistry, nuclear reactions can break apart individual atoms and recombine them. Nuclear reactions are differentiated from chemical ones because they go beyond mere electron interactions, into the nucleus of an atom, and break apart, rearrange, and recombine the internal constituent parts of atoms, protons and neutrons. Examples could include the fusion of hydrogen into helium that powers the sun, uranium enrichment to create nuclear fuel, or radioactive decay in general. Only through nuclear reactions can one thing truly become something completely different. Within the field of chemistry, there is no 'different,' only temporary recombination.
I guess that would be when a "regular" particle meets an antiparticle - in that case, 100% of the mass of both particles will be released as energy.Next come nuclear reactions, where usually something like a fraction of one percent of the matter gets released as energy. Chemical reactions release about a million times less energy than nuclear reactions.
Only in that to make plutonium or tritium for nuclear bombs you need a reactor. While the reactors that make these materials can also be used to generate electricity, they usually don't. Also the types of reactors usually used to generate electricity are not usually designed to efficiently make these materials.
Yes, gamma rays are often emitted during nuclear reactions as a form of high-energy electromagnetic radiation. They are released when excited atomic nuclei transition to a lower energy state. Gamma rays have a very high penetrating ability and are used in various applications such as medical imaging and sterilization.
Gamma radiation comes from the nuclei of atoms, usually as a result of nuclear reactions or radioactive decay. It is the most energetic form of electromagnetic radiation and can be produced by processes such as nuclear fission, nuclear fusion, or from certain types of radioactive decay.
Isotopic mass refers to the mass of a specific isotope of an element, which is determined by the number of protons and neutrons in its nucleus. Each isotope of an element has a different mass due to the variation in neutron count, even though they have the same number of protons. The isotopic mass is usually expressed in atomic mass units (amu) and is crucial for calculations in chemistry and nuclear physics, including determining atomic weights and understanding nuclear reactions.
