The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). Correct Answer: E = hv = h x c / λ nm to m or m to nm Correct Answer: 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? Correct Answer: 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 three...
