Shapes of Molecules and Ions

OCR Chemistry A -Shapes of Molecules and Intermolecular forces
Covers Shapes of Molecules and Ions

To construct simple electron dot and cross diagrams to describe the electron arrangements in ions and covalent and dative bonds

Bonding in simple molecular structure types – typical physical properties (MP, solubility in water, electricity conductivity)

Use electron pair repulsion principle to predict, explain and name the shapes of simple molecules such as BeCl2, BF3, CH4, NH3, H2O and SF6 as well as ions such as NH4+
