Solutions

Chapter 21, Problem 21.5QAP
Interpretation Introduction

(a)

Interpretation:

The binding energy for the emitted electron is to be calculated.

Concept introduction:

The minimum energy required to remove an electron from its orbit to a reason is called binding energy. It is represented as Eb.

Interpretation Introduction

(b)

Interpretation:

The kinetic energy if Mg

Kα source had been used.

Concept introduction:

The kinetic energy is the product of electronic charge, potential difference and the charge. It is represented as Ek.

Interpretation Introduction

(c)

Interpretation:

The peak was an XPS and not an Auger electron peak is to be verified.

Concept introduction:

Both AES (Auger Electron Spectrometer) and XPS (X-ray Photoelectron Spectrometer) are used in spectrometer. The sample is detected by the use of these spectrometers. The XPS peaks change according to the source, and it is different for different sources.

Interpretation Introduction

(d)

Interpretation:

The net energy of electron with source AlKα and the binding energy of electron in NaNO3.

Concept introduction:

The minimum energy required to remove an electron from its orbit to a reason is called binding energy. It is represented as Eb. The kinetic energy is the product of electronic charge, potential difference and the charge. It is represented as Ek.
