Chapter 10, Problem 10A.2AST

Interpretation Introduction

Interpretation:

The process in which ${}_{\text{64}}{\text{Gd}}^{\text{145}}$ undergo to reach stability has to be given.

Concept Introduction:

Proton-rich nuclei have a low proportion of neutrons and lie below the band of stability.

These isotopes tend to decay in such a way that the atomic number is reduced. For example, proton-rich ${}_{\text{15}}{\text{P}}^{\text{29}}$ is radioactive and decays by emitting a positron, a process that converts a proton into a neutron and raises the final n/p ratio:

  ${}_{\text{15}}{\text{P}}^{\text{29}}{\stackrel{}{\to }}_{\text{14}}{\text{S}}^{\text{29}}{\text{+}}_{\text{+1}}{\text{e}}^{\text{0}}$
