Chapter 20, Problem 71AP

Interpretation Introduction

Interpretation:

The radioactive chemical reaction for the preparation of Astatine is to be written in both normal and abbreviated forms.

Concept introduction:

In a balanced radioactive decay,

${\displaystyle \sum \text{Reactant mass number = }{\displaystyle \sum \text{Product mass number}}}$

And

${\displaystyle \sum \text{Reactant atomic number = }{\displaystyle \sum \text{Product atomic number}}}$

In a balanced radioactive decay, the subscript present on the individual particles represents the atomic number while the superscript represents the atomic mass.

While writing the abbreviated form of any radioactive reaction, the reactant is written first followed by parenthesisthatcontains the bombarded particle first and then the emitted particle. After this, the product is written.
