What is Balmer series of hydrogen spectrum?
The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.
How do the Balmer series of lines in the hydrogen spectrum arise?
The Balmer series of atomic hydrogen. These lines are emitted when the electron in the hydrogen atom transitions from the n = 3 or greater orbital down to the n = 2 orbital.
Is Balmer series an emission?
The Balmer series is the portion of the emission spectrum of hydrogen that represents electron transitions from energy levels n > 2 to n = 2. These are four lines in the visible spectrum. They are also known as the Balmer lines.
Why are there only 4 lines in the emission spectrum of hydrogen?
Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released… hence, mono-electronic hydrogen has many spectral lines.
How do you read the Balmer series?
The Balmer series is characterized by the electron transitioning from n ≥ 3 to n = 2, where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-α, 4 to 2 is H-β, 5 to 2 is H-γ, and 6 to 2 is H-δ.
How many Balmer lines are in the spectrum?
Balmer lines are historically referred to as “H-alpha”, “H-beta”, “H-gamma” and so on, where H is the element hydrogen. Four of the Balmer lines are in the technically “visible” part of the spectrum, with wavelengths longer than 400 nm and shorter than 700 nm….Balmer series (n′ = 2)

What is the hydrogen emission spectrum?
The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom.
What is the wavelength of the line in the Balmer series of hydrogen?
486 nm
The wavelength of the line in the Balmer series of the hydrogen spectrum corresponding to the transition is 486 nm.
How many series are there in hydrogen spectrum?

What are the wavelengths of the hydrogen spectrum?
The visible spectrum of light from hydrogen displays four wavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum number n equals 2.
What is the emission spectrum of hydrogen?

| 656.2 | red |
| 486.1 | blue-green |
| 434.0 | blue-violet |
| 410.1 | violet |
How is the hydrogen spectrum-Balmer series named?
These series of radiation are named after the scientists who discovered them. When a hydrogen atom absorbs a photon, it causes the electron to experience a transition to a higher energy level, for example, n = 1, n = 2.
What is the name of the Balmer series?
Balmer series The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2. There are four transitions that are visible in the optical waveband that are empirically given by the Balmer formula.
Which is the only series of hydrogen emission spectrum?
This series of hydrogen emission spectrum is known as Balmer series. This is the only series of lines in the electromagnetic spectrum that lies in the visible region. The value, 109,677 cm-1, is called the Rydberg constant for hydrogen.
