The protons live in the nucleus.
Atomic # = # of protonsP+

The neutrons also live in the nucleus.
Atomic mass - # of protons = # of neutrons
The electrons live outside the nucleus.
# of protons = # of electrons

Electron Cloud
USE THIS INFORMATION TO CREATE A MODEL FOR THE CARBON ATOM
atomic # = # of protons
atomic mass - # of protons = # of neutrons
# of protons = # of electrons
THINK OF EACH RING AS A HIGHWAY…ONLY SO MANY CAN FIT ON EACH ROAD
CHECK YOUR WORK!
SKETCH OUT THE ATOM
Draw a sketch of the carbon atom in your packet. Be sure to label your protons like this
Be sure to label your neutrons like this
Be sure to label your electrons like this

LET’S REVIEW
Before we get started, can you tell me
The number of protons? The number of neutrons? The number of electrons?
