7. Wave and a Particle Planks Duality of Nature Electron is both a wave and a particle

8. The rules Aufbau principle States that the structure of each successive element isobtained by adding one proton to the nucleus and oneelectron to the lowest energy orbital that is available. Hund’s rule For an atom in the ground state that the number ofunpaired electrons is the maximum possible and theseunpaired electrons have the same spin Pauli Exclusion Principle That two particles of a certain class cannot occupy the samefour quantum numbers

9. Pauli’s Exclusion Principle No two electrons can have the same four quantum numbers orbital

10. Quantum Numbers n,l,m,s n = energy level l = suborbital s, p,d,f m = number of electrons s = spin
