4. My Soapbox Key Takeaways:
Keep up with make-up work…if you miss class, go to my website and put yourself to work
Do the homework…not copy it, not ignore it, not half-#$^ it
Pay attention in class…heads down or resting = not paying attention
Make use of my tutoring and make-up schedule
NEVER GIVE UP WHEN YOU DON’T GET IT
Remember: Winning is hard work

7. The Bohr Model Objectives:
Diagram Bohr’s model in terms of energy levels of electrons.
Understand that when heated, electrons in metal ions absorb energy and move to higher energy levels then release energy as light when they return to their original level.
Know the properties of a wave

Thomson
Rutherford

11. Niels Bohr Danish scientist
Theorized that electrons orbit around the nucleus and that light is emitted by electron movement between energy levels
Student of Ernest Rutherford
Rutherford was a student of JJ Thomson
Niels Bohr

12. WARNING: The Bohr Model only works for Hydrogen
Similar concept to the solar system
The electrons orbit around the nucleus in different energy levels
Accounts for the 3 subatomic particles
Based on the line emission spectrum of excited atoms
Wait, what? We’ll come back to this
The Bohr Model
WARNING: The Bohr Model only works for Hydrogen

13. Creating a Bohr Model 3 Steps
Draw a circle and write the number of protons and neutrons  This is your nucleus
Draw a circle around the nucleus  This is your n = 1 energy level. It holds up to 2 electrons.
After you fill the 1st orbital, draw another circle  This is your n = 2 energy level. It holds up to 8 electrons
Repeat as needed
Never draw another circle without filling the previous orbital

15. The Wave 3 key components Discuss with your group:
Wavelength: The distance between crests of a wave
Frequency: The number of crests of a wave that pass a given point in a given amount of time (directly related to energy)
Amplitude: The height of a wave (we will not discuss this)
Discuss with your group:
What happens to frequency when wavelength is increased?
If a wave has a high frequency, what can you predict about the wavelength?
The Wave

16. Every element emits light of only certain wavelengths (colors) when their atoms are excited
It is like the DNA of elements
Line Emission Spectra

17. Hydrogen’s Emission Spectrum

18. How it Works 3 Phases: http://www.youtube.com/watch?v =8TJ2GlWSPxI
Energy is absorbed by an electron
The electron jumps to a higher energy level (further from nucleus)
The electron loses the extra energy and falls to its original energy level  As it falls it gives off light (a photon)
=8TJ2GlWSPxI
How it Works

19. The Light We See Light moves like a wave
The visible light we see is based on the electron arrangement of an atom
Violet is the highest in frequency and energy
Red is the lowest in frequency and energy
The Light We See

An ion occurs when an atom gains or loses electrons to form a bond. Draw the Bohr model for an atom of Cl that gains one electron when it bonds with Na.
What is the resulting charge?
