TIME FOR THE REAL PHOTON GAME

Do the Right Thing

One Version C Gameboard, One Version D Gameboard

Decide at your table which one of you will use Version C and which will use Version D.

Atoms on Earth always start in ground state

Place your electron on the lowest energy level possible (n = 1).

The electron will only move up to a higher energy level if it can GAIN energy from an outside source.

Step 1

Placed in Bunsen Burner: Gain up to 600 kJ/mole

If you have gameboard C, you start at -800 kJ/mole. With the addition of 600 kJ/mole, you have many choices for where to end up!

If you have gameboard D, you can only get to level 2.

NO PHOTON IS CREATED WHEN AT ATOM GAINS ENERGY.

Step 2

Go Directly to Level 3 Note: if you have gameboard C, this may have been

a drop in energy resulting in creation of an Infrared photon. If so, draw a BLACK arrow between level 4 and level 3 and label as “IR, 80 kJ/mol”.

If you have gameboard D, this was NOT a drop in energy that created a photon (but you have gained some potential energy!!!)

Step 3

Go Directly to Level 2

Everybody will create a photon here! Calculate the energy of the photon you have produced and draw an appropriately colored arrow (with kJ/mole label) that describes the photon produced.

Step 4

Struck by a spectrum of Ultraviolet Photons:

Gain between 300 and 700 kJ/mole

Step 5

FREE FALL (you decide how far).

Draw in an arrow of the appropriate color and label (show energy value).

Step 6

Go directly to Level 1

Step 7

Struck by a spectrum of Visible Photons: gain between 170 and 300 kJ/mole

Step 8

Collide with the Sun: Gain Limitless Energy

Step 9

Drop 2 Levels

(if you are on level 2, drop to level 1)

Step 10:

Zapped by Electricity: Gain between Zero and 700 kJ/mole

Step 11

FREE FALL (you choose how far)

Step 12

Collide with the Sun: Gain Limitless Energy

(You may stay in place if you like)

Step 13

FREE FALL!
