Sulfur ion (S2 )

IONS, MOLECULES, AND COMPOUND - LAB 

PROBLEM: 
Can models help understand ions, molecules, and compounds?

HYPOTHESIS:

MATERIALS:  Polylab molecule set

Chlorine diatomic molecule (Cl2) Hydrogen nitrate, a compound

For this exercise you will need the following color balls and connections:

Small orange and red = oxygen (11); large green = chlorine (5) ; small yellow = aluminum (2); large orange  = sodium (4); small blue = nitrogen (5); large black = carbon (2);  small white connected with rod = hydrogen (3); large yellow = sulfur (4);  connections (27 ) *note: hole means it needs electrons (i.e. N^-3 ); connector means it gives electrons (i.e. Al⁺³)

Build the following molecular models looking at the formula on the table.  Ions would have an incomplete connection (see sulfur ion), diatomic molecules will have 2 of the same connected, and   after you have built them have your instructor check if they are correct.  For each of the molecules describe how the molecule is different from the rest, how many atoms make up the molecule, and which elements are parts of the molecule in the "conclusions."

Draw the model for each of the ion, molecule, or compound that you created?
