The wave function for the 2pz orbital in the hydrogen atom is c2pz 5 1 4!2p a Z a0 b 3/2 se2s/ 2 cos u where a0 is the value for the radius of the first Bohr orbit in meters (5.29 3 10211), s is Zr/a0, r is the value for the distance from the nucleus in meters, and u is an angle. Calculate the value of c2pz 2 at r 5 a0 for u 5 0 (z axis) and for u 5 908 (xy plane).

This drawing shows a human body system. what is the primary function of this body system?
