Unit+1

This area of study focuses on the historical development of and the relationship between, the Periodic Table and atomic theory. Students investigate trends and patterns as well as use subshell notations to describe electronic configurations. Students explore the link between the electronic configuration of an element and the type of bonding in which it participates. Students are introduced to many of the major qualitative and quantitative ideas fundamental to chemistry including empirical and molecular formulas and the mole concept. They undertake practical activities that build their understandings of the Periodic Table. **Outcome 1: The Periodic Table**  On completion of this outcome students should be able to explain how evidence is used to develop or refine chemical ideas and knowledge. 


 * //Key Knowledge//**
 * The Periodic Table
 * Historical development from Mendeleev to Seaborg.
 * Trends and patterns of properties within the Periodic Table: atomic number, types of compounds formed, metallic/non-metallic character, chemical reactivity of elements.
 * Atomic Theory
 * Historical development of the model of atomic theory with contributions from Dalton to Chadwick;
 * Limitations of the model of atomic theory;
 * Mass number, isotopes, calculation of relative mass, electronic configuration including subshells.
 * The mole concept including empirical and molecular formulae, percentage composition, Avogadro’s constant;
 * Interpretation of data from mass spectrometry.

This area of study focuses on the structure, properties and applications of materials.

Students investigate how the bonding were developed to explain the properties of materials. Students use these models to explain the properties and structure of metals, ionic compounds, and molecular, covalent network lattice and covalent layer lattice substances. The investigate the properties of alkanes and alkenes including some isomers. Students examine the reactions that occur in addition polymerisation and the properties of addition polymers. They explore the role of surfaces in the application of nanotachnology.

**Outcome 2: Materials**  On completion of this unit the student should be able to use models of structure and bonding to explain the properties and applications of materials. **//Key Knowledge//**  = =
