REVIEW: How do radius, IE, and core charge relate? Compare the data below, does it make sense given what you know about these two atoms?
Fluorine is one electron shy of a full outer shell. Toss an electron onto it and watch the energy.
Across boron to fluorine, core charge climbs and radius shrinks. Watch what that does to electron affinity.
Three atoms with EA blank — look at how their electrons sit.
Electron affinities across the representative elements. Blanks mean no stable anion — never a measured zero.
Pick two atoms that can share a pair. Watch who pulls harder.
