(a) Consider a carbon atom in its ground state. Would such an atom offer a satisfactory model for the carbon of methane? If not, why not? (Hint: Consider whether a ground state carbon atom could be tetravalent, and consider the bond angles that would result if it were to combine with hydrogen atoms.)
(b) Consider a carbon atom in the excited state:

- Schrodinger and de Broglie suggested a ‘Wave—particle duality" for small particles—that is, if electromagnetic radiation showed some particle-like properties, then perhaps small punicles might exhibit same wave-like properties. Explain. How does the wave mechanical picture of the atom fundamentally differ from the Bohr model? How do wave mechanical arbitals differ from Bohr’s orbits? What does it mean to say that an orbital represents a probability map for an electron?arrow_forwardDo atoms in excited states emit radiation randomly, at any wavelength? Why? What does it mean to say that the hydrogen atom has only certain discrete energy levels available? How do we know this? Why was the quantization of energy levels surprising to scientists when it was first discovered?arrow_forwardQ2. 22 (a) Write down the Hamiltonian of a molecule having M nuclei and N electrons with a dear definition for each term. (b) Derive the binding energy for the H2 molecule in terms of Coulomb (J), exchange (K) and overlap (S) integrals using valence bond (VB) theory. Write down the singlet and triplet wavefunctions for an H₂ molecule using VB theory. (c) Draw the MO-diagram for a general diatomic molecule. Show the electronic configuration of F2*, F2 and discuss their bond properties and relative stabilities.arrow_forward
