IN.C. Chemistry I
C.2. Atomic Structure and the Periodic Table
C.2.2. Describe how the subatomic particles (i.e., protons, neutrons and electrons) contribute to the structure of an atom and recognize that the particles within the nucleus are held together against the electrical repulsion of the protons.
C.2.3. Determine the number of protons, neutrons, and electrons in isotopes and in those isotopes that comprise a specific element. Relate these numbers to atomic number and mass number.
IN.ICP. Integrated Chemistry and Physics
ICP.7. Nuclear Energy (fission and fusion)
ICP.7.2. Differentiate among protons, neutrons and electrons and determine the number of these subatomic particles in each atom.
ICP.7.3. Understand that the stability of nuclei depend on their numbers of neutrons and protons.
IN.P. Physics I
P.7. Modern Physics
P.7.1. Explain that electrons, protons and neutrons are parts of the atom and that the nuclei of atoms are composed of protons and neutrons, which experience forces of attraction and repulsion consistent with their charges and masses. Distinguish elements from isotopes.
