How many lines of emissions does hydrogen have?
four
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).
What is the emission of hydrogen atom?
Hydrogen molecules are first broken up into hydrogen atoms (hence the atomic hydrogen emission spectrum) and electrons are then promoted into higher energy levels. Suppose a particular electron is excited into the third energy level. It would tend to lose energy again by falling back down to a lower level.
Why does hydrogen only emit 4 colors?
Although hydrogen has only one electron, it contains many energy levels. When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels. Those photons appear as lines.
How many emission lines are possible?

What is the electron affinity of hydrogen?
Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom….Elements.
| Z | 1 |

| Element | 1H |
| Name | Hydrogen |
| Electron affinity (eV) | 0.754 195(19) |
| Electron affinity (kJ/mol) | 72.769(2) |
Why do hydrogen and helium have different spectral lines?
There are different interactions present in helium atom such as electron-electron repulsion and nuclei-electron repulsion. So, due to the presence of different energy levels, there is emission of different wavelengths in helium atom. Therefore, hydrogen emission wavelength is different from helium emission wavelength.
Why are there so many lines in hydrogen spectrum Class 11?
Different excited electrons adopt different routes to return to various lower energy levels or the ground state.As a result ,they emit different amount of energies and thus produce a large number of lines in the atomic spectrum of hydrogen.
What would be the maximum number of emission lines for atomic hydrogen?
Therefore, there are 5 emission lines in the given spectrum of the atomic hydrogen that can be seen with the naked eye. Hence, the correct option is B. Note: The students should keep in mind that not all the emission lines in the Balmer series can be seen with the naked eye.
How do the spectral lines of hydrogen occur?
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 maximum number of spectral lines emitted by hydrogen?
6-number of lines are emitted.
How many visible lines make up emission spectrum of hydrogen?
The hydrogen spectrum has four lines in the visible region at 656, 486, 434, and 410 nm. atoms.
What can emission lines tell us?
Emission and absorption lines can tell us a great deal about a distant celestial source, but they only occur under certain conditions. Emission lines from an element will appear if there are atoms of the element present the atoms are in a low-density gas
Why does hydrogen have so many spectral lines?
hence, mono-electronic hydrogen has many spectral lines. Although hydrogen has only one electron, it contains many energy levels. When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels.
What is the emission spectrum of hydrogen?
The hydrogen emission spectrum is a spectrum produced by the emission of light by hydrogen atoms in excited states. There, when we pass a beam of white light through a sample of hydrogen gas, then the atoms absorb energy. After that, the electron in the hydrogen atom gets excited to a higher energy level.
