Question

what are isotopes ? Give example of isotopes . Write two applications of isotopes .​

Answer 1

The answer is " Isotopes

Isotopes are atoms of same element having same atomic number but different mass numbers

Application of Isotopes

1)An isotope Uranium is used as a fuel in nuclear reactor.

2)An isotope of cobalt is used in treatment of cancer.

3)An isotope of iodine is used in treatment of goitre.

Answer 2

One member of a family of chemical elements that has the same chemical properties (the same atomic number) but differs in mass. Isotopes have the same number of protons and electrons, but a different number of neutrons.

Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth's crust.

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes
