WebJan 5, 2024 · The order of ionic radii for halides and hydride is apparently as follows: F X − < C l X − < B r X − < H X − < I X −. Why is the hydride ion so large, even larger than bromide which has filled 3d and 4p subshells? Some claim that it is because the ratio of positive to negative charge is 0.5, which is an unusually small ratio. But this ...
