For a: The isotopic symbol of the above atom will be $_{53}^{131}\textrm{I}$

For b: The isotopic symbol of the above atom will be $_{77}^{192}\textrm{Ir}$

For c: the isotopic symbol of the above atom will be $_{62}^{153}\textrm{Sm}$

Explanation:

The isotopic representation of an atom is: $_Z^A\textrm{X}$

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

For a: Iodine-131

Atomic number of iodine = 53

Mass number of iodine = 131

Symbol of iodine = I

The isotopic symbol of the above atom will be $_{53}^{131}\textrm{I}$

For b: Iridium-192

Atomic number of iridium = 77

Mass number of iridium = 192

Symbol of iridium = Ir

The isotopic symbol of the above atom will be $_{77}^{192}\textrm{Ir}$

For c: Samarium-153

Atomic number of samarium = 62

Mass number of samarium = 153

Symbol of samarium = Sm

The isotopic symbol of the above atom will be $_{62}^{153}\textrm{Sm}$
