Activity Sheet
Name ________________________________________ Date ________________
When you look closely at the tip of a sharpened pencil, you will see that it is made
of graphite. Going deeper, graphite is made of carbon atoms. Deeper still, each
carbon atom is made of protons, neutrons, and electrons. In this lesson, you will
explore these subatomic particles and their charges.

1.
Label the nucleus (protons, neutrons) and electrons in the drawing of a carbon
atom above. 2.
Draw a line between the subatomic particle and its charge. !
proton no charge
electron positive charge
neutron
negative charge
3. Would the following subatomic particles attract each other or repel one another?
Two protons _____________
Two electrons ____________
A proton and an electron _________
