What are the two main types of nuclear reactions?

The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.

Does a nuclear reaction destroy matter?

The total mass of the matter can change during a nuclear reaction, the mass loss can convert into energy, which is called the nuclear power. So we can say that a nuclear reaction creates/destroys matter, if we define matter only as its mass.

Is angular momentum conserved in nuclear reaction?

Nuclear reactions are subject to classical conservation laws for charge, momentum, angular momentum, and energy (including rest energies). We have accepted conservation of energy and momentum. In all the examples given we assume that the number of protons and the number of neutrons is separately conserved.

What are the conservation laws in nuclear?

The law of Conservation of Nuclear Number states that the sum of protons and neutrons among species before and after a nuclear reaction will be the same. In radioactive decay, a proton can be converted to a neutron and a neutron can be converted to a proton (beta-decay).

What two quantities do not change during a nuclear reaction?

In both nuclear and chemical reactions, two physical quantities are seen to be conserved and unchanging: the number of particles and the total charge. A constant number of particles in nuclear reactions does not imply that mass is conserved.

How is a nuclear equation balanced?

Nuclear reactions also follow conservation laws, and they are balanced in two ways: The sum of the mass numbers of the reactants equals the sum of the mass numbers of the products. The sum of the charges of the reactants equals the sum of the charges of the products.

Is Thorium emits a beta particle a chemical reaction?

Classify each of the following as a chemical reaction, a nuclear reaction, or neither: Thorium emits a beta particle. Two atoms share electrons to form a bond. A sample of pure sulfur releases heat as it slowly cools….Section 24.1 Nuclear Radiation.

Chemical Nuclear
Bonds broken & formed Nuclei emit particles and/or rays

Why is U 235 the most common nuclear fuel instead of the more abundant U 238?

The isotope U-235 is an important common nuclear fuel because under certain conditions it can readily be split, yielding a lot of energy. Uranium 238 on the other hand is not fissionable by thermal neutrons, but it can undergo fission from fast or high energy neutrons. Hence it is not fissile, but it is fissionable.
