Module 6: Electronic Structures and Periodic Properties of Atoms

At the completion of this chapter, students should be able to:

• Define orbital, state the four types of orbitals, and the maximum number of electrons in each
• Write the electron configuration for the ground state of atoms and ions
• Use Hund’s rule to draw the orbital diagram of the ground state of an atom or ion
• Perform calculations that convert frequency to wavelength and/or energy
• Use the Rydberg equation to calculate the emission lines of the hydrogen atom
• Use the Pauli exclusion principle to state the quantum numbers that describe an electron in a given orbital
• Arrange atoms and ions in order of diameter
• State the periodic trends seen for the first ionization energies
• Define electron affinity
• State the name of each main group as well as the major chemical properties of each group
