Describing Atoms

Atomic Number = # of protons

the # of protons = the # of electrons

Atomic Mass Number = protons + neutrons.

Page 11: Warm Up Question

Valence Electrons: Only the electrons in the outer shell of an atom

Think About It…

Make a Brace Map of an Atom. Break it down into its three subatomic particles and list a few characteristics of each.
