  3. Hydrogen is a bit of an anomaly because it behaves like an alkali metal chemically but like a halogen physically...bottom of the group (astatine and iodine) then bromine is a liquid, and chlorine and fluorine are gases. Hydrogen fits well with this trend if it s at the top of group 17. Halogens also bcome lighter in...
