Question

explain with example isotopes and isobars give two uses of isotopes?​

Answer 1

Answer:

Isobar is that element which differs in the chemical property but has the same physical property. So, we can say that isobars are those elements which have a different atomic number but the same mass number. Their chemical property is different because there is a difference in the number of electrons. It has the same atomic mass but different atomic no. Because an additional number of neutrons compensates the difference in the number of nucleons.

The example of two Isotopes and Isobars is iron and nickel. Both have the same mass number which is 58 whereas the atomic number of iron is 26, and the atomic number of nickel is 28.

Uranium-235 is used for nuclear fission and as a fuel in nuclear reactors.

An isotope of cobalt is used in the treatment of cancer.

An isotope of iodine is used in the treatment of goiter.

Isobars: Isobars are the same elements having different atomic number but same mass number. USES OF ISOTOPES: (a) It is used as a uranium for the nuclear reactor (b) It is used as cobalt for treating blood cancer. ... Example, hydrogen has 3 isotopes - protium (1H1), deuterium (2H1) and tritium (3H1).
