Element T-Shirt Rubric



Element T-shirt Research Project

Due Monday December 17, 2012

Your job is to design a t-shirt for your assigned element. Your t-shirt should contain the following information:

First, give a thorough description of the element:

• the name of the element

• the atomic number

• the atomic mass

• the chemical symbol

• a diagram of the atom (be sure to include protons, neutrons, and electrons)

• chemical/physical properties

Next, include where the element can be found:

• the period and group/family in which it is found (include group name, if applicable)

• is it a metal, nonmetal, metalloid, or noble gas?

• do some research and find out some uses of the element

Challenge yourself:

• Who discovered the element?

• When was it discovered?

• Where was it discovered?

• origin of name

The t-shirt must be neat, organized, and contain all of the above information. You will need to do some research on your element. Here are some resources:

•

•

• You may use an encyclopedia or other approved resources!

Directions for making an atomic model

Step 1: Find out the number of protons in an atom of your element. (# protons = atomic number)

Step 2: Find the number of electrons. By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons.

Then place electrons in their shells:

Shell 1: 2 electrons

Shell 2: 8 electrons

Shell 3: 18 electrons

Shell 4: 32 electrons

Shell 5: 32 electrons

Shell 6: 18 electrons

Shell 7: 8 electrons

Step 3: Find the number of neutrons. The atomic weight is basically a measurement of the total number of particles in an atom’s nucleus. To find the mass number, round the atomic weight to the next whole number.

(atomic mass) = (# protons) + (# neutrons)
