Chapter 21.1, Problem 1PE

Interpretation Introduction

Interpretation:

From the given nuclear reaction X has to be identified.

Concept Introduction:

On accordance with law of conservation of mass, for any chemical reaction, total masses of reactants and products must be equal.

  ${\displaystyle \sum \text{reactant}\text{mass}\text{number=}{\displaystyle \sum \text{product}\text{mass}\text{number}}}$

Similarly for any chemical reaction, sum of the reactant atomic number is equal to the sum of the product atomic number.

  ${\displaystyle \sum \text{reactant}\text{atomic}\text{number=}{\displaystyle \sum \text{product}\text{atomic}\text{number}}}$

${}_Z^{A}X$, where X is the element, A is the mass number and Z is the atomic number of the element.
