SC3. Students will use the modern atomic theory to explain the characteristics of atoms.
SC3.a. Discriminate between the relative size, charge, and position of protons, neutrons, and electrons in the atom.
SC3.d. Explain the relationship of isotopes to the relative abundance of atoms of a particular element.
SP2. Students will evaluate the significance of energy in understanding the structure of matter and the universe.
SP2.b. Explain how the instability of radioactive isotopes results in spontaneous nuclear reactions.
GA.SPS. Physical Science
SPS1. Students will investigate our current understanding of the atom.
SPS1.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.
