Vedclass · Answer

(A) $(i)$ Atomic number: The atomic number of an element is defined as the total number of protons present in the nucleus of an atom of that element. It is denoted by $Z$. For example,a nitrogen atom contains $7$ protons,so its atomic number is $7$.$(ii)$ Mass number: The mass number of an element is the sum of the total number of protons and neutrons present in the nucleus of an atom of that element. It is denoted by $A$. For example,a boron atom has $5$ protons and $6$ neutrons,so its mass number is $5 + 6 = 11$.Uses of isotopes:$1$. An isotope of uranium is used as a fuel in nuclear reactors.$2$. An isotope of iodine is used in the treatment of goitre.

Explain with examples $(i)$ Atomic number,$(ii)$ Mass number. Give any two uses of isotopes.
