Get started for freeAlveoli are the tiny sacs of air in the lungs (see Problem 5.136 ) whose average diameter is \(5.0 \times\) \(10^{-5} \mathrm{~m} .\) Consider an oxygen molecule \(\left(5.3 \times 10^{-26} \mathrm{~kg}\right)\) trapped within a sac. Calculate the uncertainty in the velocity of the oxygen molecule. (Hint: The maximum uncertainty in the position of the molecule is given by the diameter of the sac.)
Draw the shapes (boundary surfaces) of the following orbitals: (a) \(2 p_{y},\) (b) \(3 d_{z^{2}}\) (c) \(3 d_{x^{2}-y^{2}}\), (Show coordinate axes in your sketches.)
A helium atom and a xenon atom have the same kinetic energy. Calculate the ratio of the de Broglie wavelength of the helium atom to that of the xenon atom.
Calculate the total number of electrons that can occupy (a) one \(s\) orbital, (b) three \(p\) orbitals, (c) five \(d\) orbitals, (d) seven \(f\) orbitals.
Use the Aufbau principle to obtain the ground-state electron configuration of technetium.
