NAME: CLASS PERIOD:
Disciplinary Core Ideas (NGSS) Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. (HS-PS1-1) Student performance objectives At the end of this unit students should be able to:
1) Describe early milestones in the development of modern atomic theory. 2) State and apply the law of conservation of mass and the law of definite proportions. 3) State the premises of Dalton's atomic theory. 4) Describe J. J. Thomson's experimental evidence for the existence of electrons. 5) Describe Rutherford's scattering experiments and show how the results of the experiments imply the
existence of atomic nuclei. 6) List the three most important particles that all atoms are composed of, and describe their charges and
relative masses. 7) Understand the concept of atomic weight. 8) Describe how isotopic masses and isotopic abundances are measured experimentally using mass
spectrometry. 9) Describe the basic structure of the periodic table.
