Lab Station 1: Covalent Bonding
1. Use the element symbols and electrons to create the electron-dot notation for each element
on the table.
2. Re-arrange the elements and lone electrons to see where shared electron pairs can be made.
3. Replace the shared electron pairs with single, double, or triple bonds.
4. Draw the final structure below:
5. What is the formula for this molecule?
Chorline Nitrate
Lab Station 2: Ionic Bonding (electron transfer)
1. Use the element symbols and electrons to create the electron-dot notation for each element
on the table.
2. Use the arrows to show how the cation(s) will transfer their valence electrons to the anion(s).
3. Create the final lewis structure showing the proper charges for each ion.

Lab Station 4: Atomic Structure
1. Count how many balls you have of each color.
2. Determine which color represents the protons, neutrons, and electrons.
3. Determine the name of the element based on the number of protons, neutrons, and electrons.
4. Complete the atomic structure by placing the correct particles in the nucleus, and the correct
number of particles in each shell.
5. Draw the atomic structure below (you do not need to draw individual particles inside the
nucleus, simply state how many you have of each type of particle):
Cl
Pink(Neutron):18
Hairy(Proton)17
Red(electron)17
6. What is the name of this element?
Chlorine
