Textbook Problem

Write a balanced equation for the radioactive decomposition of 87Rb.

Interpretation Introduction

Interpretation:

The balanced equation for the radioactive decomposition of Rubidium-87 has to be written.

Concept Introduction:

Balancing nuclear reaction equation: The balanced nuclear reaction should conserve both mass number and atomic number.

  • The sum of the mass numbers of the reactants should be equal to the sum of mass numbers of the products in the reaction.
  • The sum of atomic numbers (or the atomic charge) of the reactants should be equal to the sum of atomic numbers (or the atomic charge) of the products in the reaction.
Explanation

The Rubidium-87 undergoes decomposition by emitting beta particle and becomes stable Strontium-87. The balanced reaction is written as per the law of conservation of mass; sum of atomic and mass number on both sides are equal.

The balanced equation for the radioactive decomposition of Rubidium-87 is R3787
