## Why Do The Balmer Lines Of Hydrogen Get Closer Together As You Go Towards Shorter Wavelengths

In the Balmer series as the wavelength decreases the lines appear closer together and are weaker in intensity. I understand why the lines appear closer together (because as the energy levels increase the gap between successive energy levels decreases).

## Why do lines on the emission spectrum get closer together?

The spectrum lines become closer together the further from the nucleus. This is because the energy levels are closer together further from the n energy levels they are.

## What is the shortest wavelength in the Balmer series?

In the hydrogen spectrum, the shortest wavelength in the Balmer series is the lambda.

## What is the wavelength of the line in the Balmer series of hydrogen?

The wavelength of the line in the Balmer series of the hydrogen spectrum corresponding to the transition is 486 nm.

## What does the Balmer series tell us?

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.

## Why do energy levels get closer together as they increase?

As the energy levels increase, the pull on the electrons to the nucleus decreases gradually; therefore, they are closer when n=3,4,5.

## Which emission line in the hydrogen spectrum occurs at the longest wavelength?

The visible photons in the hydrogen spectrum are the Balmer series lines. The lowest energy and longest wavelength photon corresponds to the 3→2 transition and is red.

## What did the Balmer series suggest about hydrogen?

Niels Bohr proposed a model for the hydrogen atom in 1913 that described discrete energy states associated with a fixed electron orbit around the nucleus. Importantly, an atom cannot discharge energy while its electrons are in stationary states.

## What is the Balmer formula How does it explain the hydrogen spectrum?

Johann Balmer, a Swiss mathematician, discovered (1885) that the wavelengths of the visible hydrogen lines can be expressed by a simple formula: the reciprocal wavelength (1/λ) is equal to a constant (R) times the difference between two terms, 1/4… In principles of physical science: Compilation of data.

## What is the difference between Lyman and Balmer series?

Lyman and Balmer’s series are hydrogen spectral line series that arise from hydrogen emission spectra. The key difference between Lyman and Balmer series is that the Lyman series forms when an excited electron reaches the n=1 energy level whereas the Balmer series forms when an excited electron reaches the n=2 energy level.

## What happens to the distance between energy levels as they increase?

Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. Ionic radius is the distance from the nucleus to the outer edge of the electron cloud of an ion.

## Why do lines converge at higher energies?

As electrons move further away from the nucleus, the electron shells become closer together in terms of space and energy, and so lines converge towards the end of the spectrum.

## Why do electrons closer to the nucleus have less energy?

In the lowest energy level, only one orbital exists that can carry a maximum of two electrons. Because more protons are present in the nucleus, the force of attraction between the protons and electrons is stronger. This results in the electrons closest to the nucleus having less energy.

## What is the shortest wavelength?

Gamma rays have the shortest wavelength and the highest energy among the other waves in the electromagnetic spectrum. The wavelength of the gamma rays is less than 0.01 nanometers.

## How many spectral lines are in the Balmer series?

The series of visible lines in the hydrogen atom spectrum is called the Balmer series. This series of spectral emission lines occur when the electron transitions from a high-energy level to the lower energy level of n=2. Hence, the correct answer is Option (A) 5 lines.
