WINSTONCH [101]

<u>Answer:</u> The atomic symbol of the given element is $_{53}^{130}\textrm{I}$

<u>Explanation:</u>

The general isotopic representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents the atomic number of the element

A represents the mass number of the element

X represents the symbol of an element

For the given isotope: 130-iodine

Mass number = 130

Atomic number = 53

Hence, the atomic symbol of the given element is $_{53}^{130}\textrm{I}$
