Chapter 20, Problem 76AE

(a)

Interpretation Introduction

Interpretation: Whether it is true that a radioactive nuclide which decays from 1.00×1010 atoms to 2.5×109 atoms in 10 minutes has a half-life of 5.0 minutes or not needs to be determined.

Concept Introduction: The time required for the concentration of a reactant to decrease to half of its original value is called half-life of a reaction.

(b)

Interpretation Introduction

Interpretation: Whether it is true that nuclides with large Z values are observed to be α particle producers or not is to be determined.

Concept Introduction: The decay of a radioactive nucleus produces the alpha particles, due to unstable condition of the nucleus.

(c)

Interpretation Introduction

Interpretation: Whether it is true that nuclides require a greater proton-to-neutron ratio for stability, as the value of Z increases or not is to be determined.

Concept Introduction: In naturally occurring and stable nuclei the neutron-to-proton ratio increases with the increase in atomic number.

(d)

Interpretation Introduction

Interpretation: Whether it is true that “light” nuclides having twice as many neutrons as protons, are expected to be stable or not is to be determined.

Concept Introduction: An atom which is having a specific number of neutrons and protons in its nucleus is called a nuclide.
