Which of the following is radioactive metal?
Naturally occurring radioactive metals include polonium (Po), francium (Fr), radium (Ra), actinium (Ac), thorium (Th), protactinium (Pa), uranium (U), neptunium (Np), and plutonium (Pu) [1]. U is one of the most important radioactive metals for modern world.
What type among the following element is radioactive in nature?
Detailed Solution. Polonium is a radioactive element. Henri Becquerel (1852-1908) observed that there are certain elements which emit radiation on their own and named this phenomenon as radioactivity and the elements known as radioactive elements.
What is a type of potential energy?
Various Forms of Potential Energy
- Elastic Potential Energy.
- Electrical (Electromagnetic) Potential Energy.
- Gravitational Potential Energy.
- Nuclear Potential Energy.
How are radioactive elements produced in a nuclear reactor?
These radioactive elements are produced in nuclear reactors and accelerators. There are different strategies used to form new elements. Sometimes elements are placed within a nuclear reactor, where the neutrons from the reaction react with the specimen to form desired products.
Where are radioactive elements found on the periodic table?
The latest element on the periodic table have not been found in nature. These radioactive elements are produced in nuclear reactors and accelerators. There are different strategies used to form new elements. Sometimes elements are placed within a nuclear reactor, where the neutrons from the reaction react with the specimen to form desired products.
What happens to radioactive elements when they decay?
Typically these primordial radioisotopes have half-lives so long they are stable for all practical purposes, but when they decay they form what are called secondary radionuclides. For example, primordial isotopes thorium-232, uranium-238, and uranium-235 can decay to form secondary radionuclides of radium and polonium.
What kind of isotopes are produced by nuclear fission?
Nuclear fission from nuclear power plants and thermonuclear weapons produces radioactive isotopes called fission products. In addition, irradiation of surrounding structures and the nuclear fuel produces isotopes called activation products.
