Question

Rank the following elements by electron affinity, from most positive to most negative EA value.

Rank from most positive to most negative. To rank items as equivalent, overlap them.

Most positive Most negative

Answer 1

1.Electron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom. The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion. Either convention can be used.Whereas ionization energies are always concerned with the formation of positive ions, electron affinities are the negative ion equivalent.THANKS
