EXAM 3:
1) s orbitals are ______________ symmetric.
2) A 3p orbital has _______ radial nodes. (write a #)
3) The splitting of a beam of silver atoms induced by an inhomogeneous magnetic field is due to the fact that an electron has an intrinsic _________ angular momentum.
4) The ______________ equation of a helium atom cannot be solved exactly.

6) The atomic unit of energy is called the ____________.
7) Hartree-Fock equations are solved by the _________-consistent procedure.
8) Wavefunctions must be ________________ with respect to interchange of any two electrons
9) True or False? For the hydrogen atom in the absence of any external field, the 2s orbital is lower in energy than the 2p orbital. TRUE FALSE
10) The splitting of a hydrogen atom
Explanation / Answer
1 - s orbitals are ____spherically__________ symmetric.
2 - A 3p orbital has ___1____ radial nodes. (1 angular 1 radial total = 2 node)
3- The splitting of a beam of silver atoms induced by an inhomogeneous magnetic field is due to the fact that an electron has an intrinsic ___ spin(quantized) = 1/2______ angular momentum.
4- The _______wave function_______ equation of a helium atom cannot be solved exactly.
5- The variational method will always yield an energy that is ___always greater________ than or equal to the true value.
6- The atomic unit of energy is called the Hartree energy in the Hartree system and the Rydberg energy in the Rydberg system.
7- Hartree-Fock equations are solved by the __self _______-consistent field (SCF) procedure.
8- Wavefunctions must be ___antisymmetric_____________ with respect to interchange of any two electrons.
9- TRUE (the 2s electron penetrates more inside the charge of the 1s electron. The 2s is therefore less shielded from the attractive force of the nucleus than the 2p and is lower in energy.)
10 - The splitting of a hydrogen atom
