Suppose that the uncertainty in determining the position of an electron circling an atom in an orbit is 0.4 Angstrom. What is the uncertainty in its velocity?

Suppose you have an electron in an excited state of a hydrogen atom. You find that you can just ionize this electron with 1460 nm light. What was the principal quantum number n of that electron?

German physicist Werner Heisenberg related the uncertainty of an object's position (Ax) to the uncertainty in its velocity (Av) h Ax 2 4xmAv where h is Planck's constant and m is the mass of the object. The mass of an electron is 9.11 x 10-31 kg. What is the uncertainty in the position of an electron moving at 5.00 x 10° m/s with an uncertainty of Av = 0.01 x 10ʻ m/s? Ax 2 m

At the Cincinnati zoo you can see the 45.4 kg cheetah run and it flew across the pen at 65.4 miles per hour – your  super de Broglie powers of observation allowed you to notice that the de Broglie wavelength of the cheetah was what (in units of meters)? Pay attention to units! Note: 1609 meters = 1 mile

If an electron has an uncertainty in its velocity of 2.30 m/s, what is the uncertainty (in meters) in its position?

Be sure to answer all parts How fast must a 143.9−g baseball travel in order to have a de Broglie wavelength that is equal to that of an x-ray photon with λ= 75.0 pm? Enter your answer in scientific notation please.

Rutherford used a beam of alpha particles for his scattering experiment. What is the de Broglie wavelength of an alpha particle moving at a velocity of 2.45 × 107 meters per second?

What set of quantum numbers describes the last e in Strontium, Sr, atom? n= 1= m- m. =
