.Stable radioactive elements are naturally transmuted.In contrast, chemical transmutation occurs when fundamental particles are used to interact with atoms of one element.Here, we will learn about artificial transmutation.
What is Artificial transmutation?
.To produce oxygen, an * particle was first fired at a nitrogen nucleus.Radioactivity is induced in the element that is produced.
For bombardment, the following particles will be used:1H11H3) (
Protons, neutrons, and deuterons contain positively charged nuclei, therefore they repel positively charged nuclei and are ineffective projectiles.Alternatively, neutrons possess no charge at all and are thought to be the best projectiles.The product that is created during a neutron bombardment depends upon the neutrons' speed.Neutrons penetrate the nucleus slowly while high-speed neutrons pass through it.Nuclear reactions are more efficient when high-speed neutrons are used as opposed to slow neutrons, known as thermal neutrons.
Examples of Artificial Transmutation
Examples of artificial transmutation are as follows:
(2*4 extrm[N] + (2*4 extrm[He])
(0.27*13 extrm[Al] + 0.04*2 extrm[He])
As shown by the examples of artificial transmutation above, the three "conservation laws" do apply to nuclear reactions:
It is important to note that nuclear reactions are subject to the three "conservation laws":
Artificial Transmutation Equation
Equations represent the conversion of one element to another.A number of protons indicates artificial transmutation.To convert an element, the left side will keep the bombarding fundamental particles, whereas the right side will hold the final element together with any subatomic particles.

Artificial Transmutation Chemistry
Transmuted radioactive elements are called tracer elements.It is also used to study the environmental effects of some pesticides and for medical purposes.Radioactive isotopes of phosphorus contained in calcium phosphate trace phosphorus excess in plants.
A transmutation of transuranic elements artificially has helped manage radioactive waste.This is accomplished by reducing the proportion of nuclei with a significant half-life.Nuclear fission occurs when fast-moving neutrons bombard these nuclei.Hence, the fission reaction can reduce the half-lives of plutonium and other actinides, which are many thousands of years.The fission products are shorter-lived (their half-lives are almost less than 30 years).
.Radiation from the resulting products is radioactive, but it will decay in short order.
