Wild Bill’s Wild Bohr Quiz

Niels Bohr’s model of the hydrogen atom, was the primary reason for the understanding of energy levels.

Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the

diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that

energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form

of light. He figured the light rays to be quantized, meaning only certain frequencies of the light rays

can be seen. In turn, he reasoned that the hydrogen atoms themselves were quantized and, that they only

can exist in certain energy levels. When the atoms absorb specific amounts of energy, they exist for a

small period of time in higher energy levels. But as soon as these atoms lose their energy, they move

back down to the lower levels of energy. His theory went on to state how the hydrogen atom can move up

and down the energy levels, one level at a time, and c!

an never stop in between. Every hydrogen atom is made up of a single electron – proton system. Because

the negative electron is attracted to the positive proton, potential energy is created inside the atom.

He figured that the farther away the electron is from the proton, the greater the potential energy is

inside. In conclusion, since hydrogen atoms emit light energy in specific frequencies, the hydrogen atom

must be within a specific energy level and nothing else. The different wavelengths help to determine the

different colors emitted from the atom. The greater the wavelength, the faster the atom can be filled

and jump to a higher level.

Bohr developed his theory after studying the work of Einstein’s ideas on the photons of energy. He used

these ideas to explain the amount of energy collected in the bright-line spectrum. He then used

mathematics to determine the different energy levels of hydrogen. Bohr was able to prove the other

spectral lines for hydrogen in the ultraviolet and infrared places of the electromagnetic spectrum.

Overall, his model of the hydrogen atom helped to provide an explanation for different energy levels,

color formation, and frequencies.
