For each of the following orbitals, provide a perspective sketch of the orbital in the Cartesian x, y, z coordinate system. Determine the number of angular nodes and the number of radial nodes in the orbital, and describe where any angular nodes are located. (For instance. the 2Px orbital has an angular node in the yz-plane.)
a) 1s b) 3px c) 3dx2-y2 d) 3dxz
