Excitation of the electron can promote it to energy levels described by other sets of quantum numbers. Worksheet 4-1 Atomic Spectra.
When an electron falls from a higher energy level to a lower energy level how is the energy released.
Atomic emission spectra and the quantum mechanical model worksheet. Atoms become excited when they absorb energy. Bowling Ball – Daltons model of Atom. The quantum-mechanical model of the atom A.
They then emit energy in the form of light as they return to a less excited state. Start studying Chemistry Unit 3 Lesson 6. When energy is added an electron can jump up to a higher energy orbit and when the electron relaxes back to a lower energy orbit the difference in energy is emitted as a photon of light.

This model also referred to as the planetary model of the atom explained emission spectra in terms of electrons moving between different stationary orbits that have different levels of energy.
Unlike the Bohr model however the quantum mechanical model does not specify an exact path the electron takes around the nucleus. Bohrs model of the atom which was so successful in explaining the line spectra of single-electron atoms was a total failure in all attempts to describe multielectron atoms. Hoberman Sphere – Atom is mostly empty space.
