A spectroscope separates light into its component wavelengths, revealing a line spectrum that is unique to each element.
Bohr explained this phenomena by suggesting that electrons revolve around the atom’s nucleus in orbits of fixed energy
The electrons are restricted to certain energy levels, and the energy is quantized Quantized means the electrons have a specific amount of energy at each energy level
If an electron absorbs energy, it becomes excited and can jump to a higher energy level In order for the electron to return to its original energy level, it must release the same amount of energy The lines that are produced in a line spectrum are a result of the electron falling back to its original position
Electrons can exist at different levels around the nucleus of an atom These levels, correspond to the quantum numbers
