Textbook Problem

Write balanced equations for each of the processes described below.

a. Chromium-51, which targets the spleen and is used as a tracer in studies of red blood cells, decays by electron capture.

b. Iodine-131, used to treat hyperactive thyroid glands, decays by producing a β particle.

c. Phosphorus-32, which accumulates in the liver, decays by β-particle production.

(a)

Interpretation Introduction

Interpretation: Balanced chemical equations for the given nuclear decay processes are to be stated.

Concept introduction: Nuclei of radioactive element decompose in various ways. There are two major categories. One involves a change in mass number of the decaying nucleus, while others do not. Types of radioactive processes include α particle production, β particle production, γ ray production, electron capture and many others. Electron capture decay involves the capturing of one of the inner orbitals electrons by the nucleus.

Beta particle production decay involves the production of beta particle (10e) that is assigned a mass number zero.

A helium nucleus 24He is produced in the alpha decay process.

To determine: The balanced chemical equation for the given process.

Explanation

The balanced chemical equation for the given process is,

2451Cr+10e2351V

Use of 51Cr in targeting the spleen and tracing the red blood cells and its decay by electron capture process is given
