The mass number of a nucleus decreases during nuclear reactions involving alpha decay, beta decay, and neutron emission. In these reactions, the nucleus loses mass as particles are emitted, resulting in a decrease in the mass number.

Nuclear Reactions involve what part of the atom?

Nuclear reactions involve the nucleus of the atom, which contains protons and neutrons. During these reactions, changes in the nucleus, such as fusion or fission, release large amounts of energy.


How do you alter nucleus of an atom?

The nucleus of an atom can be altered through processes such as nuclear reactions, which involve changing the number of protons and neutrons in the nucleus. This can lead to the formation of different elements or isotopes. However, altering the nucleus of an atom can release large amounts of energy and needs to be done carefully to control potential risks.


What energy is stored in nucleus?

The energy stored in the nucleus is nuclear energy, which is released during nuclear reactions such as fission or fusion. This energy is much more potent than chemical energy due to the large amount of energy stored in the nucleus of an atom.


In an atom the nuclear energy in held in?

In an atom, the nuclear energy is held in the nucleus, which is the central core of the atom consisting of protons and neutrons. This nuclear energy is released during nuclear reactions, such as fission or fusion, and is responsible for powering nuclear reactors and atomic bombs.


Which electromagnetic waves are produced during some nuclear reactions?

During nuclear reactions, gamma rays are produced as a form of electromagnetic radiation. Gamma rays are the most energetic and penetrating type of electromagnetic radiation, and they are produced when the nucleus of an atom undergoes a change.


What type of energy is released by a nuclear reaction?

Nuclear reactions release nuclear energy, which is the energy that holds the nucleus of an atom together. This energy is released in the form of heat and radiation during processes such as fission or fusion.


Does nuclear reaction convert matter into energy?

Yes, nuclear reactions convert a small amount of matter into a large amount of energy, as described by Einstein's famous equation E=mc^2. This means that a small portion of the mass of the nucleus is converted into energy during nuclear reactions.


What is energy from the tiniest particles of matter called?

Energy from the tiniest particles of matter is called atomic or nuclear energy. This type of energy is released during nuclear reactions within the nucleus of atoms.


What type of energy is stored in an atomic nuclei?

The energy stored in an atomic nucleus is nuclear energy. This energy is released during nuclear reactions such as fission or fusion.


How can the conversion of mass to energy be explained in the context of nuclear reactions?

In nuclear reactions, mass can be converted into energy according to Einstein's famous equation, Emc2. This means that a small amount of mass can be converted into a large amount of energy. This process occurs during nuclear reactions, such as nuclear fission or fusion, where the nucleus of an atom is split or combined, releasing a tremendous amount of energy in the form of radiation.


How is nuclear binding energy related to the mass defect and what implications does this relationship have for nuclear reactions and stability?

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.


What is the role of uranium electrons in nuclear reactions?

The role of uranium electrons in nuclear reactions is to facilitate the process of nuclear fission, where the nucleus of the uranium atom splits into smaller nuclei, releasing a large amount of energy. The electrons help maintain the stability of the atom and interact with other particles during the reaction.
