Chapter 25, Problem 77SAE

Interpretation Introduction

(a)

Interpretation:

The distinction between electron and positron is to be defined.

Concept introduction:

Based on different radioactive decay there are different processes in which an unstable atomic nucleus loses energy and emits radiation, this radiation can be of different type and are in the form of particles like alpha, beta, etc.

Interpretation Introduction

(b)

Interpretation:

Distinction between half-life and decay constant is to be described.

Concept introduction:

During transition metal-ligand complex formation, different colors for different ligand complex are seen due to the absorbance of different wavelength of light by different ligands.

Interpretation Introduction

(c)

Interpretation:

Distinction between mass defect and nuclear binding energy is to be described.

Concept introduction:

There is a difference between the experimentally determined mass of the nucleus and mathematically added mass of neutrons and protons known as mass defect. Dissociation energy for nucleons is known as binding energy.

Interpretation Introduction

(d)

Interpretation:

The difference between nuclear fission and fusion is to be described.

Concept introduction:

The phenomenon of the nucleus to split into fragments and the combination of lighter nuclei are known as fission and fusion respectively.

Interpretation Introduction

(e)

Interpretation:

The difference between primary and secondary ionization is to be described.

Concept introduction:

The phenomenon of an atom getting positive or negative charge by getting or losing electrons is known as ionization.
