Properties and Structures of Matter 1-2

IQ1  How do the properties of substances help us to classify and separate them? 

1.1a explore homogeneous mixtures and heterogeneous mixtures through practical investigations:

• using separation techniques based on physical properties

1.1b explore homogeneous mixtures and heterogeneous mixtures through practical investigations:

• calculating percentage composition by weight of component elements and/or compounds

IQ2  Why are the atoms of elements different from one another? 

2.1 classify the elements based on their properties and position in the periodic table through their:

-    physical properties

-    chemical properties

2.2  Model the atom’s discrete energy levels, including electronic configuration and spdf notation 

2.3 investigate energy levels in atoms and ions through:

-   collecting primary data from a flame test using different ionic solutions of metal salts

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

2.4 calculate the relative atomic mass from isotopic composition  

2.5 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 mass number (nucleon number)

2.6 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 reactions
