Chapter 18, Problem 14QRT

(a)

Interpretation Introduction

Interpretation:

The missing particle in the nuclear equation has to be filled.

    $\text{P}\text{u}\stackrel{}{\to }\text{H}\text{e}\text{+}\text{?}$

Concept Introduction:

Radioactive nuclides undergo disintegration by emission of radiation.  This is a natural transmutation reaction where the nuclide of one element is converted into nuclide of another element.  Radioactive decay happens naturally.  This can also be done artificially in the laboratory by means of bombardment reaction.  Bombardment reaction is the one where the target nuclei is hit by a small fast moving high-energy particle to give a daughter nuclide and a small particle such as proton or neutron.  This can be represented in form of a nuclear equation.  A balanced nuclear equation is the one in which the sum of subscripts on both sides are equal and sum of superscripts on both sides are equal.
