reason for fractional atomic masses

application of radioactive isotopes​

Answer 1

Answer:

Hello❤

ISOTOPES:

✍Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.

✍All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.

Characteristics:

✍Isotopes are atoms of the same element with same number of electrons and protons but different number of neutron.

✍ Since they have different numbers of neutrons, this affects the mass number. Mass number determines the physical properties such as boiling/melting/density etc.

✍The atomic masses of most elements are fractional because they exist as a mixture of isotopes of differentmasses.

Applications of radioactive isotopes:

✍  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.

Thanks ❤❤!!

Answer 2

❤️❤️The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses.The fractional atomic masses arise because of this mixture. Radioisotopes are commonly used in industrial radiography, which uses a gamma source to conduct stress testing❤️❤️
