Flame Emission Spectroscopy
(Is this valid?)
Yes, although that is a rather pretentious name for the "flame test," as it is usually referred to.
My word:
HybridisationThe mixing of atomic orbitals to form new orbitals suitable for bonding. It happens in methane (CH4). Think about the carbon atom connected to 4 hydrogen atoms. The carbon atom's valence shell has 2 s electrons, and 2 p electrons. They are of different energy levels, so how can the methane molecule be tetrahedral (as measured)? It must be that the s and p orbitals are merged together to form a 'hybrid' orbital by an average of the single s orbital and the three p orbitals. This creates 4 equal sp
3 orbitals, which can explain the equally energetic bonds in methane, giving its tetrahedral shape. It is this mixing of orbitals that is referred to as hybridisation.
