Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups.....

b) Element B has greator atomic radius because , as we move From left to right atomic no. increases and therefore the force too increase which makes small atomic radius
.
