Valence Bond Theory - A model that attempts to reconcile the shapes of molecules with those of atomic orbitals through the concepts of orbital overlap and hybridization (429). hybridization - a postulated process of orbital mixing to form hybrid orbitals (430). hybrid orbitals - an atomic orbital postulated to form during binding by the mathematical mixing of specific combinations of nonequivalent orbitals on a given atom (430). sp hybrid orbital - an orbital formed by the mixing of one s...

Electronegativity trend (p. 21) - correct answer Moving from left to right across a period, electronegativity INCREASES. Moving down a group from top to bottom, electronegativity DECREASES. Principal Quantum Number: "n" (p. 19) - correct answer Represents the shell an electron occupies, denotes the energy level or size of an orbital. Is the coefficient number in an electron configuration e.g. for 3p^2, n=3 Angular Momentum Quantum Number: "l" (p. 19) - correct answer Represents the sub...

Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...
