So I have an answer key that says the order, from least to greatest, of Germanium, Silicon, and Carbon's electron affinities, with the answer being below
Smallest numeric value (most favorable, releases E) C < Si < Ge
But this doesn't follow the periodic trends we've learned, plus looking it up the opposite is found.
So wouldn't carbon have the largest electron affinity, then silicon, then germanium? Or am I misreading this?
