Understand the general idea of the quantum mechanical description of electrons in an atom, and that it uses the notion of three-dimensional wave functions, or orbitals, that define the distribution of probability to find an electron in a particular part of space
An orbital is the quantum mechanical refinement of Bohr’s orbit. In contrast to his concept of a simple circular orbit with a fixed radius, orbitals are mathematically derived regions of space with different probabilities of containing an electron.
The electron orbital simulator (EOS) is a Unity program that serves as a visual aid for learning the structure of the atom. On the left is a 3D model of the atom selected in the periodic table. Using the dropdown, you may view a simplified model of it's electron cloud or a 3D representation of the bohr model.
Each orbital is identified and characterized by three quantum numbers: n, l, and m. Principal Quantum Number, n. The principal quantum number describes the size of the orbital and may have the value of any positive (nonzero) integer.
Understand the general idea of the quantum mechanical description of electrons in orbitals; Relate the 3D shape of an orbital and how electrons are arranged within the atom to the radial distribution function; List and describe traits of the four quantum numbers that describe orbitals and specify the location of an electron in an atom
This applet displays the wave functions (orbitals) of the hydrogen atom (actually the hydrogenic atom) in 3-D. Select the wavefunction using the popup menus at the upper right. Click and drag the mouse to rotate the view.
