  1. Bellringer • COMPLETE SENTENCES!!!! • Where in an atom are the following subatomic particles located: proton, neutron, electron? • What is the charge on the following subatomic particles: proton, neutron, electron? • Who is credited with the discovery of the following subatomic particles: proton, neutron, electron?

  2. Subatomic Particles and the Nuclear Atom Objectives: 3.3 Utilizing benchmark discoveries to describe the historical development of atomic structure, including photoelectric effect, absorption, and emission spectra of elements 9.1 Identifying atomic and subatomic particles, including mesons, quarks, tachyons, and baryons Other AOD C.9.1 Describe the structure of atoms, including the location of protons, neutrons, and electrons.

  3. Three-Tab Foldable • Three tab labels: • Proton (p+) • Neutron (n0) • Electron (e-) • What is the charge on each particle?

  4. Location • Protons - ? • Neutrons - ? • Electrons - ?

  5. Relative Mass • Protons = 1 • Neutrons = 1 • Electrons = 1/1840 • What does this tell you?

  6. Actual Mass • Proton = 1.673 x 10-24 g • Neutron = ??? • Electron = 9.11 x 10-28 g • Do the math! How does the mass of an electron compare to the mass of a proton or neutron?

  7. Discovery • Proton • Discovered by Ernest Rutherford in 1920 • Neutron • Discovered by James Chadwick in 1932 • Electron • 1st subatomic particle identified • Formally identified by JJ Thomson in the late 1890’s

  8. Assignment • Exit Slip: Describe (in writing or a drawing) the structure of a typical atom. Identify where each subatomic particle is located. • Workbook: p. 19 (3-12); p. 20 (1-8)
