Answer 1

Answer:

About isotopes their characteristics

“The atoms of the same element which have the same number of protons but different number of neutrons inside their nuclei are called isotopes of that element.” Isotopes are described by writing the mass number of that isotope as a superscript only the left side (top-left side) of the symbol of the element.

Reason for fractional atomic masses

The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses. Most elements occur as a mixture of isotopes of different masses. The fractional atomic masses arise because of this mixture. ... mass = total mass of all atoms/number of atom.

Application 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.
