I nqui r yques t i on Why are atoms of elements different from one another?

Rat i onal e Students examine the structure of an atom and explore different models. Students will be introduced to the Bohr and Schrödinger models. Students investigate isotopes and use this understanding to explain radioactivity, demonstrating how isotopes can be stable and unstable.

CH11-8 Explores the properties and trends in the physical, structural and chemical aspects of matter

Dept hSt udy The following questions can be used as provocations for students to start a depth study.  

How has the model of an atom evolved over time? Why have models of the atom changed?



How has the Bohr model and Schrodinger model informed our current understanding of the atom?

Examples of communicating the above include:  Poster presentation  

Oral presentation Analysis of a documentary

 

Collaborative presentations, for example O365 PowerPoint, Apple Keynote, Google Slides, Padlet, Powtoon, mind mapping software, etc. Multimedia software

 

Infographics Podcast



eBook



If a depth study is included in the unit, the following must be included: the two Working Scientifically outcomes of Questioning and Predicting, and Communicating

 

a minimum of two additional Working Scientifically outcomes further development of at least one Knowledge and Understanding outcome

Cont ent The working scientifically skills mentioned in the outcomes should be embedded throughout the teaching and learning experiences CH11-8 Explores the properties and trends in the physical, structural and chemical aspects of matter Students: 

investigate the basic structure of stable and unstable isotopes by examining: o

their position in the periodic table

o

the distribution of electrons, protons and neutrons in the atom

o

representation of the symbol, atomic number and mass number (nucleon number)



model the atom’s discrete energy levels, including electronic configuration and pdf notation (ACSCH017, ACSCH018, ACSCH020, ACSCH022)

 

calculate the relative atomic mass from isotopic composition (ACSCH024) investigate energy levels in atoms and ions through:



o

collecting primary data from a flame test using different ionic solutions of metals (ACSCH019)

o

examining spectral evidence for the Bohr model and introducing the Schrödinger model

investigate the properties of unstable isotopes using natural and human-made radioisotopes as examples, including but not limited to: o

types of radiation

o

types of balanced nuclear reactions
