180m/173 Tl -> 180/173 Tl + ? Express your answer as a nuclear equation

Law Incorporation [45]

Answer: The nuclear equation is $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$ .

Explanation:

A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.

For example, $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$

Here, energy is radiated in the form of gamma radiation.

Thus, we can conclude that the nuclear equation is $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$ .
