Fission is another word for splitting. The process of splitting a nucleus is called nuclear fission. Uranium or plutonium isotopes are normally used as the fuel in nuclear reactors, because their atoms have relatively large nuclei that are easy to split, especially when hit by neutrons. In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). In biology, fission occurs when a cell (or body, population, or species) divides into two or more parts and the regeneration of those parts into separate cells (bodies, populations, or species). Binary fission produces two separate cells, populations, species, etc., whereas multiple fission produces more than two cells, populations, species, etc. read less

In a fission reaction, a heavy atomic nucleus is split into smaller nuclei, other particles and radiation. In a typical reaction, an atom of uranium 235 absorbs a neutron and splits into two lighter atoms, barium and krypton, emitting radiation and neutrons. Under special circumstances (the attainment...

In a fission reaction, a heavy atomic nucleus is split into smaller nuclei, other particles and radiation. In a typical reaction, an atom of uranium 235 absorbs a neutron and splits into two lighter atoms, barium and krypton, emitting radiation and neutrons. Under special circumstances (the attainment of a "critical mass") the emitted neutrons can split further atoms, which in turn bring about more splitting, producing a very fast chain reaction. Nuclear power plants exploit the process of fission to create energy. read less

Nuclear fission is a process in nuclear physics in which the nucleus of an atom splits into two or more smaller nuclei as fission products, and usually some by-product particles.

When an atom splits into two parts, either through natural decay or when instigated within a lab, it releases energy. This process is known as fission. It has great potential as a source of power, but is also has a number of safety, environmental, and political concerns attached to it that can hinder...

When an atom splits into two parts, either through natural decay or when instigated within a lab, it releases energy. This process is known as fission. It has great potential as a source of power, but is also has a number of safety, environmental, and political concerns attached to it that can hinder its use. Fission definition An atom contains protons and neutrons in its central nucleus. In fission, the nucleus splits, either through radioactive decay or because it has been bombarded by other subatomic particles known as neutrinos. The resulting pieces have less combined mass than the original nucleus, with the missing mass converted into nuclear energy. read less

Why do we apply paint on iron articles?
When iron comes in contact with atmospheric air, it gets corroded or rusted. A reddish brown colour is deposited on its surface called a s rust; which damaged the iron article. Hence, to prevent such rusting we apply paint the iron articles.
