The Heisenberg uncertainty principle can be expressed in the form
where E represents energy and t represents time. Show that the units for this form are the same as the units for the form used in this chapter:
Answer to relevant QuestionsUsing the Heisenberg uncertainty principle, calculate Δx for each of the following. a. An electron with Δv = 0.100 m/s b. A baseball (mass = 145 g) with Δv = 0.100 m/ s How does the answer in part a compare with the size ...An electron in a 10.0 nm one-dimensional box is excited from the ground state into a higher- energy state by absorbing a photon of electromagnetic radiation with a wavelength of 1.374×10-5 m. Determine the final energy ...Identify each of the following orbitals, and determine the n and l quantum numbers. Explain your answers. For hydrogen atoms, the wave function for the state n = 3, ℓ = 0, and mℓ = 0 is where σ = r/a0 and a0 is the Bohr radius (5.29 × 10-11 m). Calculate the position of the nodes for this wave function. Write the expected electron configurations for each of the following atoms: Cl, As, Sr, W, Pb, and Cf.
