A method for estimating electron affinities is to extrapolate Z_eff values for atoms and ions that contain the same number of electrons as the negative ion of interest. Use the data in the table to answer the questions that follow.

Atom or lon: (kJ mol-) Ne: 2080 Na: 4565 Mg+: 7732 Al+: 11,577 Atom or lon: E (kJ mol-) F: 1681 Ne+: 3963

(a) Estimate the electron affinity of F, and compare it with the experimental value.

(b) Estimate the electron affinities of O and N.

Atom or lon: (kJ mol-) Ne: 2080 Na: 4565 Mg+: 7732 Al+: 11,577 Atom or lon: E (kJ mol-) F: 1681 Ne+: 3963 Na+: 6912 Mg+: 10,548 Atom or lon: E(kJ mol-) O: 1314 F+: 3375 Ne+: 6276 Na+: 9540
