Atomic Structure
SPS1. Students will investigate our current understanding of the atom.
a. Examine the structure of the atom in terms of
 proton, electron, and neutron locations.
 atomic mass and atomic number.
 atoms with different numbers of neutrons (isotopes).
 explain the relationship of the proton number to the element’s identity.
