Useful information can be found on the attached chemistry data sheet. for marking purposes only. Indicate the electron configuration for cobalt. (shorthand notation acceptable: how many unpaired electrons are present in co3+. What is the empirical formula of a c,o compound that contains 53% c by mass. 2: the empirical formula of a particular compound is (bn). Its molar mass was found to be about 80 g/mol. Explain your choice for largest ionization energy in terms of atomic properties. Show the most reasonable lewis structure; include all valence electrons. Determine the formal charges (if any) present in the following species. (the species look unusual, but they do exist. : show the formal charges on the structures directly, underneath each structure indicate the overall charge. The following table will be useful for this question.
