Nuclear changes can occur through processes such as fission, fusion, and decay. Fission involves splitting heavy nuclei into smaller ones, releasing energy. Fusion combines light nuclei to form heavier ones, also releasing energy. Decay involves the spontaneous transformation of unstable nuclei into more stable ones, emitting radiation in the process.

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 a nuclear accident occur?
A nuclear accident can occur due to equipment failure, human error, or natural disasters. This can lead to the release of harmful radiation, posing serious risks to human health and the environment. Proper maintenance, training, and safety protocols are essential to prevent nuclear accidents.
Where does the reaction occur in nuclear fission?
Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.
What energy comes from changes in an atom's nucleus?
Nuclear energy comes from changes in an atom's nucleus, such as nuclear fission or fusion reactions. These processes release large amounts of energy in the form of heat and radiation.
Where is the nuclear energy produced in a nuclear reactor?
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
What is the process by which the nucleus of an atom changes so that a new element is formed?
Nuclear transmutation is the process by which the nucleus of an atom changes, resulting in the formation of a new element. This can occur through radioactive decay, nuclear fission, or nuclear fusion, where the number of protons in the nucleus changes, leading to the creation of a different element.
What is the decay process does radium 226 undergo including the nuclear changes that occur?
Radium-226--------------------Radon-222 + alpha
Do nuclear materials occur naturally?
Yes, that is where we get the nuclear material for our reactors, by mining it from the Earth. Though it does not occur in high concentrations, we have to concentrate it ourselves.
What nuclear changes occur when lithium forms in stars?
Lithium forms in the stars when the light nuclei are forced together and mix with yield energy. Because the mass of the combination will be less than the sum of the masses of the individual nuclei this will result to nuclear fusion.
What causes the process of tansmutation?
Transmutation is caused by the rearrangement of atoms within a substance, leading to a change in its elemental composition. This can occur through processes like nuclear decay, radioactive decay, or nuclear reactions. Transformation of one element into another can also occur through artificial means in laboratories.
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
What are reflections that occur at changes in impedance?
Return loss refers to the reflections that occur at changes in impedance.

Did the end of World War 2 represent a clear and radical break from the past?
That lead us into the nuclear/space age. The change was not so radical as changes occur day to day.
When does nuclear fusion occur?
nuclear fusion is not a natural occurrence, it is when two atoms are fused together
