Arrangement of Electrons in Atoms: Chapter 4
Students will be able to:
o Explain the mathematical relationship among the speed, wavelength, and frequency of
electromagnetic radiation
o Discuss the dual wave-particle nature of light
o Discuss the significance of the photoelectric effect and the line-emission spectrum of
hydrogen to the development of the atomic model
o Describe the Bohr model of the hydrogen atom
o Discuss Louis de Broglie’s role in the development of the quantum model of the atom
o Compare and contrast the Bohr model and the quantum model of the atom
o Explain how the Heisenberg uncertainty principle and the Schrodinger wave equation
led to the edea of atomic orbitals
o List the four quantum number and describe their significance
o Relate the number of sublevels corresponding to each of an atom’s main energy levels,
the number of orbitals per sublevel, and the number of orbitals per main energy level
o List the total number of electrons needed to fully occupy each main energy level
o State the Aufbau principle, the Pauli exclusion principle, and Hund’s rule
o Describe the electron configurations for the atoms of any element using orbital
notation, electron configuration notation, and noble-gas notation.
