Scientific Understanding of the Nature of Light
1900-present
Wavelength of Light
Radio waves are longer than a football field, while gamma radiation wavelengths
are smaller than an atom
Electromagnetic Spectrum
Quantized EnergyMax Planck (1900) Studied why hot metals glow Determined that energy is
transferred in little packets of energy called a quantum of energy
Think of heating up a substance increasing not as continuous energy, but as rising up little stair steps of energy.
The Photoelectric EffectAlbert Einstein (1905) Determined that light should be
considered to act more like a particle than a wave.
Think of turning a light source on and off so fast that only one single particle of light is released—that is a photon.
Visible Light Niels Bohr (1913) Create a model that explained that
light is produced when an electron is excited to another energy level and then returns to its original position, giving off light.
His model only worked for hydrogen, but it opened up the idea that there are various energy levels where an electron can be located.
De Broglie and Heisenberg (~1925) Proved mathematically that you
cannot determine the exact location of an electron.
Became known as the “uncertainty principle.”
Schrödinger Wave Equation (1926) Created an equation that takes into
consideration that light acts as a wave and a particle at the same time.
His equation determined the probability of where an electron can be found around a nucleus
Orbitals based on Shrödinger’s Wave Equation

Calculate Average Atomic Mass
Start your homework! Calculate the average atomic mass of
Copper. It has two isotopes Cu-63 69.2% Abundance, Mass of 62.930
amu Cu-65 30.8% Abundance, Mass of 64.928
amu
Calculate the # Protons, Neutrons, and Electrons
1. Fe2. Na3. Hg4. Cl5. 51Hg
We will check it together in class.
ToonDoo Activity
Login to computer: user: school, password: Student! Open IE or Firefox, and go to www.toondoo.com In the top right corner, click on register. Create user name, password, and put in an email address
(if you don’t have one, use cps email) Once you are logged in, go to Tools, ToonDoo Maker Make a cartoon of an atom of an element (pick an
element in the second row of periodic table) In your cartoon you must include
# protons located in a nucleus # neutrons located in a nucleus # electrons located around the nucleus Bonus points will be awarded to any creativity added to
the toon (ie, research what the element is used for, and include that in the cartoon.)
Cornell Notes Ms. Barkume10/21
What is an atom?
What is an atom?
What are the properties of subatomic particles?
The smallest particle of an element that retains the property of that element; is electrically neutral; spherical
* Protons are the subatomic particle that define an atom of an element.
Summary: Finish as homework.
Cornell Notes Ms. Barkume10/21
How atoms differ?
What does the periodic table tell us about an atom?
