Please test your understanding of the concepts presented in this chapter with the corresponding Google Colab notebook:

1. Which of the following terms is neglected in the BO approximation?
   1. Electronic kinetic energy operator.
   2. Nuclear kinetic energy operator.
   3. Potential energy between the electrons and nuclei. It is the sum of all electron-nucleus Coulomb interactions.
   4. Potential energy operator arising from electron-electron Coulomb repulsions.
   5. Potential nuclear-nuclear repulsion energy operator, the sum of all nucleus-nucleus Coulomb repulsions.
2. The Slater determinant wave function is antisymmetric with respect to:
   1. The exchange of two electrons (permutation of two rows)
   2. The exchange of two spin orbitals (permutation of two columns)
   3. Both of the above
3. Name three fermion to qubit transformations currently supported by Qiskit Nature.
4. Name two fermion to qubit transformations that simulate a system of electrons with the same number of qubits as electrons.
