# In each of the following radioactive decay processes, supply the missing particle.a. 73Ga → 73Ge + ?b. 192Pt → 188Os + ?c. 205Bi → 205Pb + ?d. 241Cm + ? → 241Am

(a)

Interpretation Introduction

Interpretation: The missing particles in the given radioactive 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 mass number zero.

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

Positron 10e is a particle with mass same as electron, but its charge is opposite to that of electron.

An alpha decay process is characterized by the production of 24He.

To determine: The missing particles in the given radioactive decay process.

Explanation

The missing particle is 10e.

The radioactive decay for which the missing particle is to be determined is given below

73Ga73Ge + ?

Since, the mass number of  73Gaand73Ge is same. And the atomic number differs by +1
