HOMEWORK #17
NAME:
LET’S DIG IN!
You will most probably need to review Presentations ## 7-14 before you start!
1. Similar to the example above, draw a diagram for each of the two substances listed
below, starting from macroscopic picture (water bottle in my example) down to subatomic level (electron cloud models of Hydrogen and Oxygen atoms in my example). The
number of nucleons (protons and neutrons) for each specific element can be found
from the periodic table given in Presentation #9.
Please use a separate sheet of paper for your diagrams, make them big and beautiful!
2. List physical properties of the material under its diagram; indicate state of matter
under normal conditions (see example above: water is liquid, transparent).
3. Given the fact that all matter is made of just protons, neutrons and electrons (and
both of your diagrams should have those as your smallest blocks on the right), why is
everything around us is so diverse? What gives things their unique properties? Use
your diagrams to support your reasoning (you can write on the back of this page or on
the back of your diagram’s page).
