Model of An Atom

advertisement
Pre-AP Atomic Model Project
TEK 8.5 A: Describe the structure of atoms, including the masses, electrical charges, and
locations of protons and neutrons in the nucleus and electrons in the electron cloud.
TEK 8.5B:
Identify that protons determine an element’s identity and valence electrons
determine its chemical properties, including reactivity.
Project Instructions:
Part 1: Atom Model
1.
Choose one element from the periodic table between Lithium, atomic # 3 and Neon,
atomic # 10.
2.
Make an accurate and neat 3 dimensional atomic model representing the element you
choose.
3.
Label each part of your atom and include the name of your element
 The following must be labeled on your atom!
- Name of atom/element
- Protons
- Neutrons
- Electrons
4.
Your atom must be able to hang from the ceiling (it cannot be too large, too small or
too heavy).
5.
You may only use non-perishable items to make your model (i.e. styrofoam,
toothpicks, paperclips, string, wire, paper, cotton balls, etc.).
- Make sure the materials that you use accurately represent each atomic
particle (i.e. Size, mass)
Part 2: Element in the same group/family
1.
Choose another element from the same group/family as the element you chose for
your original model.
2.
Draw and label a Bohr model of each of the elements you chose on a separate sheet of
computer paper
3.
Identify the name of each element and the number of protons, neutrons and electrons
next to each model.
4.
Compare and contrast your two elements. List at least 2 similarities and 2
differences.
Project Essay: Write a paragraph about your atom including all the following information.
This must be written in paragraph form using correct spelling and punctuation.
Note: Only write the essay about your original atom model
 Atomic #
 What determines the identity of your element
 Mass number (atomic mass rounded to the nearest whole #)
 Number and electric charge of the protons, neutrons and electrons
 Whether your atom is metal, non-metal or metalloid
 Number of valence electrons
 Group #
 Period #
 Chemical properties
 Physical properties including reactivity
