The reaction produces more neutrons than were needed to start it.

Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
The following statement is not true: Fission is a sport where you try to catch fiss!
Atomic energy is produced when atoms of uranium235 or other fissile material split, or undergo fission. It is nothing to do with fluorescence, and I don't understand 'heat mass'
It is true that a uranium nucleus splits in the nuclear fission of uranium.
Fission is the splitting of heavy nuclei, mostly Uranium235 but also Plutonium 239, which is made to happen in nuclear fission reactors, and releases energy. Transmutation of elements occurs in this process as when the heavy nucleus splits, two lighter nuclei of other elements such as caesium, strontium, iodine, are formed, these are the fission products. Fusion is the joining together of two nuclei, the ones being experimented with being deuterium and tritium, both isotopes of hydrogen. These transmute to helium during fusion.
These are the constituents of atoms. Nuclei are made up of protons and neutrons. Useful nuclear energy is only obtained from a few nuclei which can be made to fission and release energy. The two main ones are Uranium235 and Plutonium239.
can cause lung cancer
yes, both true & false. They can work either by fission or some combination of fission & fusion. Most modern nuclear bombs use both fission & fusion to optimize for mission, size, weight, cost, etc. Total yield can vary from 100% fission to more than 95% fusion.
false
true
as the cell grows, the chromosomes become separated.
Yes. Prokayrotic cells typically divide through binary fission.
