Antimony is a group VB metalloid like arsenic but it has more metallic character and the chemistry of antimony is quite different than that of phosphorus or arsenic. SbV is not as strong a Lewis acid as AsV and in oxic sea water the stable form would be antimonate Sb OH 6 , while SbIII, like AsIII, would be SbOH 3 in anoxic ...
