Course: Chemistry I
Time Frame: 1-2 Weeks
Unit Number and Title: 4. Electron Arrangement
Summary: Students will continue to learn how the atomic model has been adapted over time to reflect
advancements in scientific understanding. The evidence of the wave behavior of particles is discussed
to explain the modern concept of atomic “orbitals.” Electron configurations will be necessary to fully
appreciate Periodicity in the next unit.
SC-HS-4.6.2, SC-HS-4.6.3
I CAN:
Explain the mathematical
relationship among the speed,
wavelength, and frequency of
electromagnetic radiation.
Discuss the dual wave-particle
nature of light.
Discuss the significance of the
photoelectric effect and the lineemission spectrum of hydrogen to
the development of the atomic
model.
Describe the Bohr model of the
hydrogen atom.
Compare and contrast the Bohr
model and the quantum model of
the atom.
Explain how the Heisenberg
uncertainty principle and the
Schrödinger wave equation led to
the idea of atomic orbitals.
List the four quantum numbers, and
describe their significance.
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.
List the total number of electrons
needed to fully occupy each main
energy level.
State the Aufbau principle, the Pauli
exclusion principle, and Hund’s
rule.
Describe the electron configurations
for the atoms of any element using

SC-HS-4.6.2
Students will:· predict wave behavior and energy transfer;· apply knowledge of waves to real life
phenomena/investigations.Waves, including sound and seismic waves, waves on water and
electromagnetic waves, can transfer energy when they interact with matter. Apparent changes in
frequency can provide information about relative motion. DOK 3
SC-HS-4.6.3
Students will understand that electromagnetic waves, including radio waves, microwaves, infrared
radiation, visible light, ultraviolet radiation, x-rays and gamma rays result when a charged object is
accelerated.
