03 Atomic Theory

Atomic Theory (Ch 3:2-4)

Objectives

Section 2: Structure of Atoms

    1. Describe the evidence for the existence of electrons, protons, and neutrons, and describe the properties of these subatomic particles.

    2. Discuss atoms of different elements in terms of their numbers of electrons, protons, and neutrons, and define the terms atomic number and mass number.

    3. Define isotope, and determine the number of particles in the nucleus of an isotope.

Section 3: Electron Configuration

    1. Compare the Rutherford, Bohr and quantum models of an atom.

    2. Explain how the wavelengths of light emitted by an atom provide information about electron energy levels.

    3. List the four quantum numbers and describe their significance.

    4. Write the electron configuration of an atom by using the Pauli exclusion principle and the aufbau principle.

Section 4: Counting Atoms

    1. Compare the quantities and units for atomic mass with those for molar mass.

    2. Define mole and explain why this unit is used to count atoms.

    3. Calculate either mass with molar mass or number with Avogadro's number given an amount in moles.

Spiritual Concept

Colossians 2:8

See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces of this world rather than on Christ.

    1. Compare the spiritual forces with the natural forces.
