Write the Lewis structure for a) HyCO (both H atoms are bound to C); b) Aso,3 H,O, ; d 6. How does the effective nuclear charge vary in the periodic table across a row in general? How in general does the effective nuclear charge vary down a column? Explain your answer in terms of atomic number and shielding of core electrons. 7. How does the ionization energy vary in the periodic table across a row in general? How in general does the ionization energy vary down a column? terms of atomic number and shielding of core electrons. 8. Explain your answer in 9. How does the electron affinity vary in the periodic table across a row in general? How in general does the electron affinity vary down a column? Explain your answer in terms of atomic number and shielding of core electrons. 10. Use the valence shell electron pair repulsion theory to determine the shape of H20 and CH4- 11. Water and oil do not mix. On the basis of the shapes you find for H:0 water and CH (oil-like) from Problem 10, determined from the bond dipoles if these two molecules have molecular dipoles 12. Explain how your answer in problem 11 explain why oil and water do not mix?
