2
Bohr vs. Electron Cloud
What is the difference between Bohr's model and the Electron Cloud Model?
3
Niel Bohr's Model (1913)
* Electrons orbit the nucleus in ciruclar paths of fixed energy (energy levels).
* useful for understanding properties of elements and their chemical interactions
*it doesn’t explain certain behaviors of electrons, except for those in the simplest atom, the hydrogen atom.
4
Electron Cloud Model (Erwin Schrödinger-1926)
*The electron cloud model uses the basic idea of Bohr's model except that electrons are not found in distinct orbits but their position can be thought of as in a cloud that has a particular energy.
5
Electron Cloud Model
* the nucleus contains protons and neutrons
* a visual model of the probable locations of electrons in an atom
*currently the accepted model of an atom
6
How did Schrödinger proposed electrons travel?
Electrons travel in waves, which means their exact positions cannot be determined.
7
Where would an electron most likely be?
Schrödinger developed an equation that could be used to calculate the chances of an electron being in any given place around the nucleus. Based on his calculations, he identified regions around the nucleus where electrons are most likely to be. He called these regions orbitals.
8
Orbitals
Orbitals may be shaped like spheres, dumbbells, or rings. In each case, the nucleus of the atom is at the center of the orbital.
