What you'll learn

This resource covers the things you need to know and be able to do for the NCEA Level 2 Achievement Standard 91164 (Chemistry 2.4) Demonstrate understanding of bonding, structure, properties and energy changes.

What you'll learn

In this resource you’ll learn to: 

• Determine the structure of atoms, ions and molecules and the attractive forces between them
• Describe bonding using Lewis structures
• Predict polarity of molecules from bond polarity and shape
• Use polar solvents – water and ethanol; non-polar hydrocarbon solvents (e.g. hexane, cyclohexane, mineral turpentine)
• Describe molecular, ionic, metallic and covalent network substances, and their physical properties
• Classify reactions as exothermic or endothermic
• Determine enthalpy changes
• Determine bond energies and how to calculate bond energy calculations.
