3. Consider the radial wavefunctions for the 4s and 3d orbitals. The 4s radial wavefunction is typed below; the 3d can be found in the book or in the table below the homework questions. R4,0=961(4a0Z)23(19248+2423)e4 (the radial wavefunction for a 4s orbital) Answer the following questions for R4,0 and R3,2. a. What is the value of the wavefunction R(r) at r=0 ? (i.e. what is R(0) ?) b. For how many values of r is R(r)=0 ? (This question is not asking for what the values for r are. Please provide the number of values for r that satisfy the conditions and brief reasoning). c. Where is R(r)>0 or R(r)
