Expert Solution & Answer

Interpretation Introduction

Interpretation: The experiments, apparatus and the type of data to test the given hypothesis is to be determined.

(a) A series of experiment involving the photoelectric effect that would test the hypothesis needs to be designed.
(b) The experimental apparatus required to test the given hypothesis should be determined.
(c)The type of data required to conclude whether the given hypothesis is correct or not should be determined.
(d) If the given hypothesis can be tested on lanthanides or actinides or not should be identified.

Concept Introduction: The light falls on the surface of the metal and results in the ejection of electron form its surface. This process is known as the photoelectric effect.

Answer to Problem 1DE

Solution: (a) When the light incident on the metal plate having one or more half-filled orbital; one does not observe the collection of electrons on the collector plate. But as the energy increases the electrons started collecting on the collector plate. This proves the given hypothesis.

(b) The experimental apparatus to study the photoelectric effect consists of the metal plate, collector plate, battery and voltmeter.
(c) The plot of stopping potential as a function of frequency is used to conclude that the given hypothesis is correct.
(d) The given hypothesis is not applicable on lanthanides and actinides because of the presence of d and f orbitals.

(a)

Explanation of Solution

The hypothesis says that that it requires more energy to remove an electron from the metal that has one or more half filled shells.

The ejection of electrons from the metal surface is tested by using the photoelectric effect by considering the apparatus consists of the metal plate on which the light is incident and the collector plate on which the electrons get collected. These two plates are connected to the electric circuit consists of battery, photodiode with amplifier and the voltmeter with reverse voltage.

When the light incident on the metal plate having one or more half filled orbital; one does not observed the collection of electrons on the collector plate. But as the energy increases the electrons starting collecting on the collector plate. This proves the given hypothesis.

(b)

Explanation:

The apparatus to study the photoelectric effect has the following parts,

A photodiode with an amplifier.
A digital voltmeter with reverse voltage.
Batteries to operate amplifier and to provide reverse voltage.
A monochromatic light source.
The incident light beam intensity must adjust using a neutral filter.

The apparatus for testing the given hypothesis is shown below:

Chemistry: The Central Science (14th Edition), Chapter 6, Problem 1DE

Figure 1

(c)

Explanation:

The data of frequency and wave length of different light source is collected and it is used in the apparatus of photoelectric effect. The different percentage transmission values as the function of intensity will be observed. The plot of stopping potential as a function of frequency will be observed from this data which conclude whether the hypothesis is correct or not.

(d)

Explanation:

The given hypothesis says that more energy is required to eject the electron form a metal having half filled orbitals as compared to those who have not. But the orbital of lanthanides and actinides are diffused in nature and they are larger in size. Therefore, they can easily accept and eject electrons by using lower energy radiation. Therefore, the given hypothesis cannot be tested on the lanthanides and actinides.

Conclusion

The ejection of electrons is tested by using the apparatus consists of metal plate and collector plate.
The experimental apparatus to study the photoelectric effect consists of the metal plate, collector plate, battery and voltmeter.
The plot of stopping potential as a function of frequency is used to conclude that the given hypothesis is correct.
The given hypothesis is not applicable on lanthanides and actinides because of the presence of d and f orbitals.
