Understanding the Third Line from the Red End in the Hydrogen Spectrum
Have you ever come across the term ‘the third line from the red end’ while studying the Bohr series of lines of hydrogen spectrum? Do you wonder what inner-orbit electron transition corresponds to this particular line? Let’s dive deeper into this topic and explore the possible answers to this question.
What is the Bohr Series of Lines in the Hydrogen Spectrum?
The Bohr series of lines is a set of spectral lines that appear in the visible spectrum of hydrogen. These lines are named after Niels Bohr, who first explained the structure of the hydrogen atom in a model based on quantum mechanics.
When an atom of hydrogen absorbs energy, its electrons jump to higher energy levels or orbitals. When these electrons return to their original orbitals, they release the excess energy in the form of electromagnetic radiation. This radiation has a characteristic wavelength and appears as spectral lines. The Bohr series of lines consists of several such lines, which are named after the energy levels involved in the electron transition.
The first four lines of the Lyman series in the Bohr model are parts of the Balmer series.
The Third Line from the Red End – How to Identify It?
In order to identify the third line from the red end, we need to consider the spectral series involved. The third line from the red end corresponds to the third line of the Balmer series. This series involves transitions between the second and higher energy levels of the hydrogen atom.
To count the third line from the red end, we need to identify the first line of the Balmer series, which is the red line with a wavelength of 656.28 nm. The second line of the series will be shorter than the first line, and the third line will be shorter than the second line. The third line from the red end in the Balmer series corresponds to a wavelength of approximately 486.1 nm.
Inner-Orbit Electron Transitions in the Hydrogen Spectra
Now that we have identified the third line from the red end, let’s explore the possible inner-orbit electron transitions involved in this line. According to the Bohr model of the hydrogen atom, when an electron jumps from a higher energy level to a lower energy level, it emits electromagnetic radiation with a specific wavelength. This wavelength corresponds to the energy difference between the two energy levels.
The possible inner-orbit electron transitions for the third line from the red end are:
Option A: 3 → 2 Transition
The 3 → 2 transition corresponds to the Balmer series, which involves transitions between the second and higher energy levels of the hydrogen atom. This transition results in the emission of light with a wavelength of 656.28 nm, which is the first line of the Balmer series. The third line of the Balmer series corresponds to the 5 → 2 transition, which has a wavelength of approximately 486.1 nm.
Option B: 5 → 2 Transition
The 5 → 2 transition corresponds to the Balmer series and involves transitions between the second and higher energy levels of the hydrogen atom. This transition results in the emission of light with a wavelength of approximately 486.1 nm, which is the third line from the red end in the Balmer series.
Option C: 4 → 1 Transition
The 4 → 1 transition corresponds to the Lyman series, which involves transitions between the first and higher energy levels of the hydrogen atom. This transition results in the emission of light with a wavelength of approximately 121.6 nm.
Option D: 2 → 5 Transition
The 2 → 5 transition involves the absorption of light with a wavelength of approximately 122.4 nm. This transition is not relevant to the third line from the red end in the Balmer series.
Conclusion
From the above analysis, we can see that the correct answer to the question “Which electronic transition of the hydrogen spectrum corresponds to the third line from the red end?” is Option B: 5 → 2 transition. This corresponds to the third line of the Balmer series, which has a wavelength of approximately 486.1 nm. Understanding the Bohr series of lines and inner-orbit electron transitions is important to gain a deeper insight into the structure and behavior of atoms.
