Explain with examples (i) Atomic no. (ii) Mass number (iii)Isotopes(iv)Isobars.Give any two uses of isotopes.

$\pink \bigstar$Answer:-$\pink \bigstar$

$\small{ \underline {\underline{\bf{Atomic \: number :}}} }$It is the number of protons present in the nucleus of an atom of an element.

$\small{ \underline{ \underline{ \bf{Mass \: number : }}}}$It is a the sum of total number of protons and neutrons present in the nucleus of an atom of an element.

$\small{ \underline{ \underline{ \bf{Isotopes : }}}}$These are the atoms of the same elements having same atomic number but different mass numbers.

$\small{ \underline{ \underline{ \bf{Isobars : }}}}$These are the atoms of different elements having the same mass number but different atomic numbers.
