Sulfur deposits in volcanic area (yellow)
you will construct monatomic ions, polyatomic ions,
diatomic molecules, and polyatomic molecules of certain compounds.
Read the material below on each of the models so you can try and connect
properties with the specific model you are creating. Remember the
models are limited in how they can make you “see” the real elements.
However, it helps you to visualize what it might really look like. The
following are the different models you will be constructing.
(Na+1 ) is missing an electron and is never found in
nature as a free element but as a compound (Na2).
Sodium reacts with water and large pieces will explore when exposed to
will be looking at an ion of sulfur (S-2
which likes to bond with a many other ions to form a very complex family
of compounds. Hydrogen sulfide (H2S) is one of these
compounds. Elemental sulfur (S2) can be found near
volcanic regions in many parts of the world.
Aluminum chloride (green=chlorine; yellow=aluminum)
the elements aluminum and chlorine, you will be constructing an ion
of aluminum Al+3 and a diatomic molecule of chlorine
Cl2. You will then combine the two and make a
molecule of aluminum chloride (AlCl3 ). Aluminum is a
silver-white metal and chlorine is a deadly gas for humans. Aluminum
chloride can explode if rapidly exposed to water.
