Chapter 16, Problem 63APP

Interpretation Introduction

Interpretation:

The equations for the given nuclear reactions need to be completed.

Concept introduction:

The equations can be balanced by matching the mass and the atomic number from both sides of the equation.

• The mass number of the atoms on the left must be equal to the mass number of the atoms on the right.
• The atomic number of the atoms on the left must be equal to the mass number of the atoms on the right.

Given:

  ${}_2^4{\text{He + }}_7^{14}\text{N}\to {\text{?+}}_1^1\text{H}$

  ${}_2^4{\text{He +}}_{13}^{27}\text{Al}{\to }_{14}^{30}\text{Si+?}$

  ${}_{\text{0}}^{\text{1}}{\text{n+}}_{\text{92}}^{\text{235}}\text{U}{\to }_{\text{38}}^{\text{90}}{\text{Sr+3}}_{\text{0}}^{\text{1}}\text{n+?}$

  ${}_{\text{12}}^{\text{23m}}\text{Mg}\to {\text{? }}_0^0\text{γ}$
