Electronic Battleship
Game Rules:
1. You will work with a partner to play Battleship®. The goal is to determine where your partner’s
ships are on their periodic table.
2. First you need to privately “hide” your ships on the periodic table by highlighting them with a
marker. The number and size of each type of ship are given below
a. 3-Destroyer –
b. 3-Cruiser –
c. 2- Battleship –
The ships may be placed on the periodic table horizontally or vertically. **No Diagonal Ships**
3. Use a folder or some kind of barrier in order to hide your periodic table.
4. You and your partner will take turns guessing the “coordinates” of the hidden “ships” by “firing”
at an element.
a. (Ex): Student A may guess 3s23p4. You may state either:
i. full (long form) electron configuration
ii. noble gas (short cut) abbreviated configuration, or
iii. just the valence electrons.
***use different configurations each time to practice all different types of configurations.
b. Student B will confirm the element saying, Sulfur. After confirmation Student B will say
“HIT” (if they hit your battleship) or “MISS”.
c. Both students must keep track of all guesses in the following table.
5. The game ends when all of one player’s ships are sunk or after time is called.
