why does helium have more emission lines than hydrogen
The main difference between the emission spectra of hydrogen and helium is Helium emission spectroscopy (plug spectroscopy) has more lines than hydrogen emission spectroscopy (plug spectroscopy).The emission spectrum of a chemical element or compound is a series of lines representing the wavelength of the electromagnetic radiation emitted by that chemical element while an electron is transitioning from a high energy level to a low energy level. emission line than hydrogen

What is hydrogen emission spectroscopy?
Hydrogen emission spectroscopy is a spectrum produced by the emission of light by hydrogen atoms in an excited state. There, when we pass a beam of white light through a sample of hydrogen gas, the atoms absorb energy. Then the electron in the hydrogen atom is excited to a higher energy level. However, because they reside in unstable high energy levels, these electrons tend to return to the ground level (the energy level in which they existed before) emitting a photon which is electromagnetic radiation that can energy equals the energy difference between the higher and lower energy levels Read more: Why does yelena create that face Furthermore, the amount of energy at each energy level is a fixed value. Therefore, the transition will always produce a photon of the same energy. We can observe the emission spectrum as colored light on a black background. However, the number of lines we can observe here is less than the number of lines of the helium emission spectrum.
What is Helium Emission Spectroscopy?
Helium emission spectroscopy is a spectrum produced by the emission of light by helium atoms in an excited state. It has more lines than the hydrogen emission spectrum. That is mainly because the helium atom has more electrons than the hydrogen atom. Therefore, more electrons are excited when we pass a beam of white light through a sample of helium, and it causes emission of more spectral lines. Therefore, different spectra (different from hydrogen) are emitted with different wavelengths for the helium atom.
What is the difference between Hydrogen and Helium Emission Spectroscopy?
Hydrogen emission spectroscopy is a spectrum produced by the emission of light by hydrogen atoms in an excited state. Helium emission spectrum, on the other hand, is a spectrum produced by the emission of light by helium atoms in an excited state. And, the basic difference between hydrogen and helium emission spectra is that the helium emission spectrum has more lines than the hydrogen emission spectrum. The reason is mainly because hydrogen has one electron per atom while helium has two electrons per atom.Read more: why are people cold after a breakup | Top Q & AF Furthermore, the significant difference between hydrogen and helium emission spectra is that there is no effect from electron-electron repulsion on hydrogen emission spectrum due to the presence of an electron in hydrogen atom while repulsion electron-electron affects the helium emission spectrum due to the presence of two electrons.
Abstract – Hydrogen and Helium emission spectroscopy
An emission spectrum is a spectrum that shows a series of lines on a black background. Here, the light emission of excited hydrogen atoms produces a hydrogen emission spectrum. Meanwhile, the light emission of helium atoms in the excited state produces a helium emission spectrum. The basic difference between the emission spectra of hydrogen and helium is that the emission spectrum of helium has more lines than the emission spectrum of hydrogen.
