Uranium is known as _________ element.
Open in App
Solution
The correct option is C radioactive and rare earth
Certain elements spontaneously emit highly penetrating rays made of subatomic particles. This is known as radioactivity and elements which emit radioactive rays are called as radioactive elements. Uranium emits radioactive rays and is a radioactive element. The rare earth elements are made up of two series of elements, the Lanthanide and Actinide series. Actinide series includes uranium. Therefore, uranium is also a rare earth element. Subatomic particles: The three main particles present in an atom are electrons, protons and neutrons. These particles are also called as fundamental particles or subatomic particles and not elements.
