AQA AS level Unit 1 Section 3 Bonding
Using the specification and books
No exam questions are included due to copy right

Including:
Homework booklets
Assessment sheets
Interactive powerpoints (rarely seen in A-level)

LESSON 5 + 6
Shapes of molecules
Objectives:
To state the rules that govern the shapes of simple molecules
To be able to draw and describe how the number of electron pairs around an atom affects the shape of the molecule
To describe what happens to the shape of a molecule when a bonding pair of electrons is replaced by a non-bonding pair
To describe what happens to the shape of a molecule when an ion is formed
