Changes in nuclear mass can happen when, say, radioactive decay occurs and a nucleus loses mass. When an unstable atomic nucleus "adjusts" to a new state, it dumps a particle or particles, and energy, and its mass decreases. Certainly nuclear fission will cause a dramatic reduction in nuclear mass, but this is the actual "breaking up" of a nucleus into smaller nuclei called fission fragments. Perhaps an example will help. The element radon is an inert gas, but it has no stable isotopes. It's most stable isotope, 222Rn, appears as a decay product of radium; it's a radioactive daughter. It turns out that 222Rn decays by alpha emission, and that means that two neutrons and two protons are kicked out of the nucleus. This will produce the radioactive daughter product polonium-218. It is possible for a nucleus to absorb a particle and gain mass. Frequently this will cause nuclear instability (if it doesn't actually initiate fission) and create a radionuclide, which is unstable and will eventually decay. But something like, say, neutron absorption (neutron capture) will result in an atomic nuclei with a greater mass than the original atomic nucleus that absorbed that neutron. It is of note that fusion knits smaller nuclei or particles together to create a larger nucleus, but this may not necessarily be considered a "simple increase" of mass in a nucleus, though the resultant nucleus will be heavier than any constituent nucuei or particles. You may want an example. If we stick some uranium-238 into an operating nuclear reactor, the 238U will absorb a neutron to become 239U, which is heavier by one neutron that the atomic nucleus that absorbed that neutron. (The 239U is unstable and decays in a couple of steps to make 239Pu, which is used as the fissile material in most nuclear bombs and as a fuel in some nuclear reactors.)

What else can I help you with?
Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
What type of nuclear decay results in the atomic number increasing by one with no change in mass?
Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.
What product of nuclear decay has mass but no charge?
Neutrons have no charge, but have mass. This is also true of neutrinos, though the mass is considered negligible for most purposes.
What is the nuclear decay equation for zirconium 97?
Zirconium does not have an isotope with mass 97.
What are radio television and the internet examples of?
Mass media
When can the law of conservation of mass be changed?
In nuclear changes.
When are changes of energy to mass and mass to energy observable?
-- In the cores of stars, where nuclear fusion reactions are taking place. -- Inside the casing of a nuclear weapon at the moment of detonation. -- In the fuel rods in the core of a nuclear power generating station. -- At the point of collision in the experimental target area in a particle accelerator.
Is the fallowing sentence true or false during nuclear reactions mass is not convserved but engery is conserved?
False. Both mass and energy are conserved during nuclear reactions, according to the principle of mass-energy equivalence stated by Einstein's famous equation, E=mc^2. This means that any changes in mass that occur during a nuclear reaction are accompanied by equivalent changes in energy and vice versa.
How are isotopes and elements different?
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Does the mass of water change going from a liquid to a solid?
No. Mass never changes, except during nuclear fission and fusion.
What is addition of mass called?
The addition of mass is typically referred to as "mass accumulation." In scientific contexts, it can also relate to concepts such as "mass transfer" or "mass flow," depending on the specific processes involved. In nuclear physics, the addition of mass might also be discussed in terms of "binding energy" when considering how mass changes during nuclear reactions.

What is the difference between nuclear energy and mass energy?
Nuclear energy is the energy released during nuclear reactions, such as fission or fusion, where atomic nuclei are altered, resulting in the release of significant amounts of energy. Mass energy, as described by Einstein's equation (E=mc^2), refers to the energy equivalent of mass itself, indicating that mass can be converted into energy. While nuclear energy specifically involves changes in atomic nuclei, mass energy encompasses the broader principle that mass inherently possesses energy. In essence, nuclear energy is a specific application of the more general concept of mass energy.
In nuclear fusion mass transforms into what?
In nuclear fusion mass transforms into energy.
What are examples of nuclear power?

Do heating matter increases its mass?
When you heat matter, it does not increase its mass. Heating matter can cause changes in temperature, density, and volume, but mass remains constant unless there is a chemical reaction or nuclear process involved.
