An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.
Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.
Spectral methods are largely used in analytical chemistry.
There are the same number of lines in the emission spectrum as the absorption spectrum.
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
The emission spectrum of an element
Niels Bohr studied the emission lines of Hydrogen.
Each chemical element has a specific emission or absorption spectrum.
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.

The emission spectrum of an element
No.
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
The emission spectrum of each element has characteristic lines for each element. Analyzing the spectrum of a star, you can figure out what elements are present, and also get an estimate on how much there is of each element. For more information, check the Wikipedia article on "emission spectrum".
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
Niels Bohr studied the emission lines of Hydrogen.
Every element has a unique emission spectrum. The lines in these spectra deduce the amount of energy released during electron transition from a higher energy level to a lower. After obtaining this spectrum, the scientists can compare them with their tabulated data.
