In the generation of most anions, the energy change (kj/mol) that _______ an electron is ________.
a.removes, positive
b.adds, positive
c.removes, negative
d.adds, negative
e.none of the above is correct.
The answer is D. An anion is a negatively charged ion, which means it has accepted an extra electron (s) from a donor ion (cation). To add an electron, energy has to be released so that the electron can be less excited and go back to its orbital level. The released energy is equivalent to the energy required to remove the electron from its orbital level.
