Module 1 | Properties and structure of matter
Content 2: Atomic structure and atomic mass
Lesson 1 | Stability of isotopes
-
investigate the basic structure of stable and unstable isotopes by examining:
– their position in the periodic table
– the distribution of electrons, protons and neutrons in the atom
– representation of the symbol, atomic number and atomic mass (nucleon number) -
investigate the properties of unstable isotopes using natural and human-made radioisotopes as examples, including but not limited to:
– types of radiation
– types of balanced nuclear reaction
Lesson 2 | Calculating relative isotopic mass
-
calculate the relative atomic mass from isotopic composition (ACSCH024)
Lesson 3 | Flame tests and emission spectra
-
investigate energy levels in atoms and ions through:
– collecting primary data from a flame test using different ionic solutions of metals (ACSCH019)
– examining spectral evidence for the Bohr model and introducing the Schrödinger model
Lesson 4 | Bohr and Schrödinger
-
model the atom’s discrete energy levels, including electronic configuration and spdf notation (ACSCH017, ACSCH018, ACSCH020, ACSCH022)
-
investigate energy levels in atoms and ions through:
– examining spectral evidence for the Bohr model and introducing to the Schrödinger model
