Wave or Quantum Mechanics
•
Taking on the ideas of Bohr, de Broglie
and Heisenberg, Schrödinger proposed
that matter can be described as a
wave.
•
In this theory, the electron is treated
as both a wave and a particle.
•
An electron is described by a

Wave Functions, Ψ
•
The
mental picture
of an electron corresponds to a wave
superimposed upon the radial trajectory of a particle orbiting the
nucleus.
•
The position of an electron is found from the solutions to the
Schrödinger Wave Equation
which predict the
“
probability
”
in a
region space where the electron is likely to be found.

The orbitals are really _______________________

Types of Orbitals
• The solutions to the
Schrödinger equation
yields the probability in
3dimensons for the
likelihood of finding and
electron about the
nucleus.
• It is these

that give rise to the
familiar hydrogenlike
orbitals that electrons
occupy.

Quantum Numbers & Electron Orbitals
_________________
are terms that arise from the
mathematics of the Schrödinger equation. They describe
location of an electron in a particular orbital much like an
address.
Each electron in an orbital has its own set of _______
quantum numbers.
