CHEM1903 - Resources for Week 5
Topics and Learning Outcomes
Atomic Electronic Spectroscopy
explain the difference between core and valence electrons distinguish between absorbance and emission spectra explain how atomic absorption spectroscopy (AAS) works convert experimental data between transmission, absorbance, and concentration if given appropriate information calculate the minimum wavelength of Bremsstrahlung radiation explain how the elements in stars and other celestial objects can be identified and their abundances measured from visible and X-ray spectrometry
Band Theory - MO in Solids
explain how band structure in insulators, semiconductors and metals arise from delocalised orbitals describe the characteristics of natural and doped semiconductors, including band-gap energy explain how semiconductors are used in solar energy collection and conversion describe chemical vapour deposition, and how it can be used to build up layers of different composition.
Polar Bonds
represent a dipole in a bond, and use electronegativity to identify the positive and negative ends describe and explain the periodic trends in electronegativity
Ionic Bonding
explain the origin of ionic bonding as a limiting case of MO theory explain why ionic interactions lead to crystals rather than small molecules define the Madelung constant, and explain its relevance to the stability of an ionic crystal explain how ionic radii influence crystal structure, and why they differ from atomic radii
