Objectives
4.1
To understand the dual nature of light
and the relationships among its energy,
frequency, and wavelength
4.5
To write electronic configurations in a
shorter notation, using the concepts of
shells, subshells, and orbitals
4.2
To use the Bohr theory of energy levels
in atoms to explain light emission and
absorption by gaseous atoms
4.6
To understand the spatial orientation of
the most common orbitals and the
uncertain nature of locating the electron
in the atom
4.3
To use quantum numbers to write the
electronic structures of the atoms in
their most stable states
4.7
To represent pictorially the energies of
the subshells in atoms and of the
electrons that occupy those subshells
4.4
To write detailed electronic
configurations for the elements, using the
permitted values for the individual
quantum numbers, the
4.8
To relate each element's position in the
periodic table to the electronic config-
uration of its atoms, and to deduce
electronic structures using the periodic
table
