Can someone assist me with this problem? I understand how to find the electron using the 0.83 angstrom measurement, but I don't understand the second portion of the problem "relative to finding it at the nucleus."

"Evaluate the probability of finding an electron in a small region of a hydrogen 1/ orbital at a distance 0.83a from the nucleus relative to finding it in the same small region located at the nucleus."

For the second part of the question, what changes is the uncertainty in position, delta x. The range of the nuclear diameter is generally taken as 1.7 x 10^(-15) metres.

Therefore, you substitute that value into the Heisenberg's indeterminacy equation and calculate the uncertainty in momentum

You then compare these uncertainties in momentum.

Return to “Heisenberg Indeterminacy (Uncertainty) Equation”
