Molecular Model Kit Lab
Name: _______________________
Examine the molecular model kit. Different atoms have different
numbers of holes to represent the number of connections that they
make with other atoms.

Connectors:
Purple connectors represent ionic bonds.
Short grey connectors represent single covalent bonds.
Long grey connectors are used when double or triple covalent bonds.
Procedure:
Construct the following and record your results in the table below.
(Draw what you see.)
1. Make a model of hydrogen gas by connecting two atoms of
hydrogen together.
2. Make a model of oxygen gas by connecting two atoms of oxygen
together.
3. Make a model of nitrogen gas by connecting two atoms of nitrogen
together.
4. Make a model of water (H2O), carbon tetrachloride (CCl4), carbon
dioxide (CO2), ammonia (NH3), and ethane (C2H6)
