CHEM1101 - Resources for Week 6
Topics and Learning Outcomes
Ionic Bonding
describe and explain the periodic trends in electronegativity explain the origin of ionic bonding explain why ionic interactions lead to crystals rather than small molecules explain the meaning of the term “lattice energy” understand how the lattice energy is influenced by size and charge of the ions explain how ionic radii influence crystal structure, and why they differ from atomic radii
Lewis Structures
draw out plausible Lewis structures for simple polyatomic molecules assign bond orders based on sharing of electron pairs, resonance structures and formal charges explain the relationship between resonance and electron delocalisation in molecular orbitals
Molecular Shape
describe the electron pair geometries and molecular shapes for molecules containing between 2 and 6 electron pairs assign molecular shapes based on Lewis structures and VSEPR theory explain the difference between polar bonds and polar molecules predict, based on molecular shape, whether a molecule will have a net dipole moment identify carbon-carbon single, double and triple bonds determine whether a molecule is polar
