Draw a lewis structure for o3 in which the central o atom obeys the octet rule, and answer the following questions based on your drawing. the number of unshared pairs (lone pairs) on the central o atom is: the central o atom forms single bonds. the central o atom forms double bonds.

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.
