Important Questions In The Overall Scheme
of Life (or
what I learned in chemistry class
yesterday!)

Give one noteworthy piece
of information indicating an electron is a
particle and then do the same thing
from a wave perspective.

When Schroedinger treated the electron as a wave he came up with
his famous “wave equation”…what
information does psi, , stand for?....what about
2

When considering the size of an
electron, what makes us rationalize why it
makes sense for to have many solutions for the same energy
value?

Give one noteworthy piece of information
indicating an electron is a particle and then do the same thing from a wave
perspective.Particle: electrons have a massWave: electrons produce interference patterns in the double slit experiment.

A series of images taken in a double-slit experiment with electrons as the electron current density is increased. Since there is only oneelectron in the apparatus at a given time, this figure shows how aninterference pattern can be built up from single-electron events.

stands for location of the electron stands for the probability of finding the electron at a specific location

When considering the size of an electron, what makes us
rationalize why it makes sense for to have many solutions for the same energy value?
Heisenberg’s Uncertainty Principle tells us that we can’t predict where an electron will be, only where it will probably be!

The given can be characterized by certain
parameters called quantum numbers…
•n (the principle quantum #)
•l (the secondary quantum #)
•ml (magnetic quantum #)

n values could be: 1, 2, 3, 4…∞
l values could be: 0, 1, 2, 3…n-1
For a given electron:
ml values could be: -l…0…+l
ms values could be: +1/2 or -1/2(spin quantum #... describes the direction of electron spin)
(describes the principle energy level)
(describes the sublevel of energy)
(describes which orbital)
