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 ${\text{E}}_{\text{b}}$.

Interpretation Introduction

(b)

Interpretation:

The kinetic energy if $\text{Mg}$

$\text{K}\alpha$ source had been used.

Concept introduction:

The kinetic energy is the product of electronic charge, potential difference and the charge. It is represented as ${\text{E}}_{\text{k}}$.

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 $\text{Al}\text{K}\alpha$ and the binding energy of electron in ${\text{NaNO}}_{\text{3}}$.

Concept introduction:

The minimum energy required to remove an electron from its orbit to a reason is called binding energy. It is represented as ${\text{E}}_{\text{b}}$. The kinetic energy is the product of electronic charge, potential difference and the charge. It is represented as ${\text{E}}_{\text{k}}$.
