Chapter 5: electron in atoms from FL Pearson Chemistry BookE.Q.:1) exactly how does the quantum mechanically model define the arrangement of electron in atoms?2) What happens once electrons in atom absorb or release brand-new energy?
Bohr proposed that an electron is discovered only in specific circular paths, or orbits, approximately the nucleus. Each feasible electron orbit in Bohr"s model has actually a solved energy.

You are watching: How is the light emitted by an atom related to its electron configuration?


The quantum mechanical model determines the permitted energies an electrons can have and also how likely it is to uncover the electron in assorted locations roughly the cell core of an atom
Each energy sub level synchronizes to one or an ext orbitals of different shapes. The orbitals describe where an electron is likely to it is in found.
Three rules-the aufbau principle, the Pauli exclusion principle, and Hund"s rule-tell you how to discover the electron construction of atom.
When atom absorb energy, their electrons move to greater energy levels. This electrons lose power by emitting light as soon as they go back to lower power level.
Einstein proposed that light might be defined as quanta of energy that behave together if they were particles.

The irradiate emitted indigenous by an electron relocating from higher to lower power level has actually a frequency directly proportional come the energy readjust in the electron.
Classical mechanics adequately describes the motions of bodies much bigger than atoms, while quantum mechanics defines the activities of subatomic particles and the atom waves
