Nuclear reactions may or may not involve nuclear transmutation. We need to split hairs here to arrive at the correct answer, and the answer involves the definition of the word transmutation. We sometimes think of transmutation as the changing of one element to another. Fission and fusion reactions do this, and many kinds of radioactive decay also convert one element into another. But there are some kinds of nuclear reactions that do not change an atom from one element to another, but instead change it from one isotope of a given element into another isotope of that element. There are a number of examples of this, and one is where isotopes of a given element absorb a neutron and become another isotope of that element. A given nucleus incorporates the neutron into its nuclear arrangement and the next heavier isotope of that element is created. If a "strict" definition of transmutation is used where it means a nuclear reaction that changes one element into another, then no, this does not always happen as illustrated above with the example of neutron absorption. If a more general interpretation of the term is used where we say that the nucleus transmutes meaning changes configuration, then yes, nuclear reactions involve nuclear transmutation.
The nuclear reactions in the Sun primarily involve fusion of hydrogen nuclei to form helium, releasing energy in the process. In a nuclear reactor, the reactions typically involve fission of heavy nuclei like uranium or plutonium, releasing energy through splitting these nuclei. The conditions and mechanisms governing the reactions in the Sun and in a nuclear reactor are different due to the vastly varying scales and environments of the two systems.
nuclei of a different element due to the change in the number of protons. This process is known as nuclear transmutation.
Well it depends, if you had one atom of uranium and a billion tonnes of thermite, the thermite would release more. Just as a 20 megatonne nuclear bomb would release more than a few grams of sulphur and iron binding. In general though nuclear reactions release far greater amounts of energy.
We are constantly bombarded by cosmic radiation from space, and background radiation from the soil. However, both are background, and we have no biological processes that depend on nuclear reactions to survive.
Most nuclear chain reactions stop before all of the reactants are used up because the reaction tends to slow down as the concentration of reactants decreases. This is due to the decrease in the probability of collisions between particles needed to continue the reaction. Additionally, the build-up of reaction byproducts can also interfere with the process as they absorb neutrons needed to sustain the chain reaction.

Carbon is not commonly used as nuclear fuel because it does not readily undergo nuclear fission reactions. Elements such as uranium and plutonium are more suitable for use as nuclear fuels due to their ability to sustain nuclear chain reactions.
Nuclear chemistry deals with the chemical reactions involving radioactive elements. Gamma radiation is due to the electromagnetic force, beta radiation is due to the weak nuclear force, and alpha radiation is due to the residual strong force (which you might call the strong nuclear force). So... if you didn't have the nuclear force, you wouldn't have alpha radiation.
No, the sun actually glows due to nuclear fusion reactions that occur in its core. In the core, hydrogen atoms fuse together to form helium, releasing a tremendous amount of energy in the form of light and heat. The corona is the sun's outer atmosphere and is much cooler than the core where nuclear fusion takes place.
Alpha rays are not typically used for practical purposes due to their low penetration power and high ionizing ability, which makes them potentially harmful to living organisms. In scientific research, alpha rays can be used in applications such as studying nuclear reactions and analyzing materials through techniques like alpha spectroscopy.

Nuclear materials refer to substances that can undergo nuclear reactions, such as uranium and plutonium. These materials are used in nuclear power plants to generate electricity or in nuclear weapons for military purposes. Special precautions are needed in handling and storing nuclear materials due to their radioactive properties.
Nuclear chemicals are substances that contain radioactive isotopes or can undergo nuclear reactions. These chemicals are typically used in nuclear processes, such as nuclear power generation, radioisotope production, and nuclear research. It is important to handle and store nuclear chemicals safely due to their potential risks to health and the environment.
The nuclear power plant changes temperature mainly due to the heat generated from nuclear fission reactions in the reactor core. This heat is used to produce steam that drives turbines connected to generators to produce electricity. Factors such as the rate of nuclear reactions, coolant flow rate, and environmental conditions can also impact the temperature of the nuclear power plant.
Nuclear energy is considered one of the most powerful man-made energy sources on Earth due to its high energy density and ability to generate large amounts of electricity. It is produced through nuclear reactions, such as fission or fusion, which release immense amounts of energy.
Nuclear binding energy is the energy needed to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of its individual particles. The mass defect is related to nuclear binding energy through Einstein's equation Emc2. This relationship affects nuclear reactions and stability because the release of energy during nuclear reactions is due to the conversion of mass into energy, and nuclei with higher binding energy per nucleon are more stable.
