WebBromine in the Periodic Table. Bromine, element symbol Br, has an atomic number of thirty-five. One can find bromine, a halogen, in the p-block, group 17, particularly in period 4. Bromine is between chlorine and iodine, and has reactivity between the two. Bromine’s electron configuration is [Ar] 3d10 4s2 4p5. WebIt may be denoted as: X + YZ → XZ + Y D i s p l a c e m e n t r e a c t i o n s f i t i n t o t w o categories: metal displacement and non-metal displacement. (a) Metal displacement: A metal in a compound can be displaced by another metal in the uncombined state. We have already discussed about this class of the reactions under section 7.2.

WebThe halogens generally show many of the properties typical of non-metals. They are poor conductors and have low melting and boiling points.
