FAQ: How can a hydrogen atom, which has only one electron, have so many spectral lines?

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.

Why do hydrogen atoms have many spectral lines?

  • 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.

Why does hydrogen spectrum contain a large number of spectral lines although it has only one electron?

A hydrogen atom contains only one electron, but this electron can be raised to higher energy states. The large number of spectral lines in hydrogen atom spectrum are due to the fact that a large number of transitions of the electron can take place between the different energy states.

Can a single hydrogen atom generate the entire line spectrum of hydrogen by itself explain your reasoning?

Explain why a single atom of hydrogen cannot produce all four hydrogen spectral lines simultaneously. A single hydrogen atom only has one electron so it can ‘t have all four transitions at the same time.

Why does hydrogen only have 4 spectral lines?

This is explained in the Bohr model by the realization that the electron orbits are not equally spaced. The electron energy level diagram for the hydrogen atom. He found that the four visible spectral lines corresponded to transitions from higher energy levels down to the second energy level (n = 2).

Why do some elements have more spectral lines than others?

Because there are many allowed energy states above the ones that are filled in an element’s ground state electron configuration there are multiple spectral lines in a given element.

What is wrong about atomic emission spectrum of hydrogen?

Answer: The number of lines does not equal the number of electrons in an atom. For example, hydrogen has one electron, but its emission spectrum shows many lines. Hence, the photons of an emission spectrum represent a variety of possible energy levels.

How many spectral lines does hydrogen atom have?

The four visible hydrogen emission spectrum lines in the Balmer series.

Which color of light corresponds to the shortest wavelength?

Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

Which element produced the smallest number of lines?

Of the elements for which there are known emission line spectra, hydrogen has the simplest spectrum with 4 spectral lines (some show 5 spectral lines)

How do electrons become excited?

When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle.

Why does hydrogen have so many spectral lines?

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.

Consider only transitions involving the n = 1 through n = 4 energy levels for the hydrogen atom. a. How many emission lines are possible, considering only the four quantum levels? 6

Why is the emission spectrum of hydrogen not continuous?

Quick answer: Atomic spectra are continuous because the energy levels of electrons in atoms are quantized. The electrons in an atom can have only certain energy levels. There is no middle ground. There is nothing between each line, so the spectrum is discontinuous.

Why do we see spectral lines?

Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…

Why does an atom give line spectrum?

When atoms are excited they emit light of certain wavelengths which correspond to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between; this series of colored lines is called a line or atomic spectra. Each element produces a unique set of spectral lines.

What do spectral lines tell us?

From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star. The width of the line can tell us how fast the material is moving. We can learn about winds in stars from this.
