Chem 219: Exam Questions With 100% Correct Answers The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). E = hv = h x c / λ nm to m or m to nm 1 m / 10^9 nm or 10^9 nm / 1 m What is the maximum number of electrons that can have the quantum numbers n = 3, ℓ = 2, mℓ = -2? The Pauli exclusion principle states that no two electrons in a given atom can share the same set of four quantum numbers (n, ℓ, mℓ, ms). This set of quantum numbers contains thr...

CHEM 219 EXAM 1 QUESTIONS WITH ALL CORRECT ANSWERS Describe how individual resonance structures impact the true structure of a molecule or polyatomic ion. - Answer Each contributing individual resonance structure contributes characteristics to the overall hybrid structure of the compound. The hybrid "averages" bond lengths and formal charges by delocalizing them among atoms that share them in each contributing individual resonance structure. On a piece of scrap paper, draw the resonance s...
