1. According to experimental data, the electron affinities of C and N are -153.9 k.J/mol and -7 kJ/mol, respectively. Does this agree with the periodic trend for electron affinity? If not, explain why these values differ from the expected trend Hint: Look at the orbital diagrams for both atoms. What happens to each of the atoms? What configurations are the most stable?) 2. The electron in a hydrogen atom moves from the n 2 state to the n- 4 state....
