Back to the atomic emmission spectrum and the atomic theory.

Question

in the 1900s, scientists observed that when a gaseous element, such as hydrogen was subjected to an electric discarge that the atoms emitted electromagnetic radiation. The light emmitted could be separated into component frequencies which forms a continuous spectrum. The atoms emit only certain wavelenghs. Each atom has its own atomic energy spectrum.
In 1913, Bohr proposed that electrons revolve around the nucleus in fixed path. These energylevels are called the principal quantum number. Bohr's study with hydrogen matched the calculated wavelengths with the wavelengths of the specified lines.

Is this better?

Answer 1

yes, better
