Chapter 18.7, Problem 18.12E

(a)

Interpretation Introduction

Interpretation:

Nuclear equation has to be written indicating the missing symbol for the given nuclear fusion reaction.

    $\text{L}\text{i}\text{+}\text{H}\stackrel{}{\to }\text{n}\text{+}\text{?}$

Concept Introduction:

Nuclear reaction can be represented in short form as nuclear equation.  This is different from chemical equation in the sense that nuclear equation considers the mass number and atomic number of the element.  Balanced nuclear equation is the one that has the same mass number balance and atomic number balance equal on both sides of equation.

(b)

Interpretation Introduction

Interpretation:

Nuclear equation has to be written indicating the missing symbol for the given nuclear fusion reaction.

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