Chapter 4 – Arrangement of Electrons in an Atom: Light, Photon Energies, & Spectra
Big Idea: Our Understanding of the structure of atoms changes as new experimental evidence and
data is obtained. The arrangement of atoms in a periodic table can be used to make predictions
about physical and chemical properties of elements and compounds.

OBJECTIVES
Students will:
1. Define the following:
Electromagnetic radiation, amplitude, wavelength,
frequency, speed of light, line spectrum, ground state,
matter wave, quantum-mechanical model, orbital,
sublevel, orbital diagram, visible spectrum, Plank’s
constant, quantum, photoelectric effect, photon,
quantum number, excited state, uncertainty principle,
electron density, principle energy level, and electron
configuration.
2. Describe a wave in terms of its frequency,
wavelength, speed, & amplitude.
3. Identify the major regions of the electromagnetic
spectrum.
4. Explain what is meant by a quantum of energy.
5. Relate the energy of radiation to its frequency.
6. Distinguish between a continuous spectrum & a line
spectrum.
7. State the main idea in Bohr’s model of the atom.
8. Describe atomic orbitals in terms of their shape, size,
& energy.
9. Determine the electron configurations of elements
using the principles of orbital energy, orbital capacity,
& electron spin.
10. Determine the number of valence electrons for
elements.
