1. What is a wave function (Psi wave in book)?

2. What is Indeterminacy principle or Uncertainty principle? In life, you are usually dependent on statistics; how does this differ from the uncertainty principle or is it similar?

3. What is Duality ? What is the wavelength of a particle? How does it depend on velocity? on mass ?

4. How do we know an electron has a wave-like nature? And a photon a particle-like nature?

5. What do we mean by Principal quantum numbers and Orbital quantum numbers of an atomic electron? What is the difference between the planetary model and the quantum model of the description?

6. A Hydrogen atom is excited to N=3 state. It eventually emits some energy and gets down to the ground state. What is the N value for the ground state? How does the atom gets rid of the energy when it makes the transition to the ground state?

7. The radioactive decays are known as alpha, beta and gamma emissions. What are they ? What kind of interactions do the first two represent?

8. What do we usually mean by a Chain reaction? Does this happen in the usual nuclear reactors?

9. What is nuclear fusion? Where do these reactions naturally take place?

10. An element X with atomic number Z and atomic mass number A undergoes a beta decay. If Y is the daughter nucleus what are the corresponding Z and A values? What if X undergoes an alpha decay? Write the reactions.

11. If an atom jumps from an excited state of N=3 with E(3) = -1.6 eV to N=2 with E(2) = -4.6 eV, what is the wavelength of the em wave? What if the atom jumps from N = 4 to N = 2 state? Is the wavelength smaller or bigger?

12. In a nuclear fission of U235 (when hit with a neutron) one of the fission products is Cs143 and 3 neutrons. What is the other product?
