Chapter 25, Problem 67A

(a)

Interpretation Introduction

Interpretation:

Balanced nuclear equation for beta emission by isotope $H$ is to be written.

Interpretation:

Concept introduction:

A proton can change into a neutron or vice versa inside the radioactive sample's nucleus through a process known as beta decay. The radioactive sample's nucleus can approach the ideal neutron/proton ratio as closely as feasible through processes like beta decay and alpha decay.

Answer to Problem 67A

Balanced reaction $H\to He+e$

Explanation of Solution

Beta decay involves the emission of a beta particle, to establish the balanced nuclear reaction for this decay, the atomic and mass number must be conserved from the initial isotope to the product of the decay. The element produced can then be identified from the atomic number. In this decay, the mass number stays the same while the atomic number increases by 1.

(b)

Interpretation Introduction

Interpretation:

The balanced nuclear equation for beta emission by $Mg$ is to be written.

Concept introduction:

A proton can change into a neutron or vice versa inside the radioactive sample's nucleus through a process known as beta decay. The radioactive sample's nucleus can approach the ideal neutron/proton ratio as closely as feasible through processes like beta decay and alpha decay.
