Using the data given in the table, deduce the state of each halogen at 20 ° C . Group 17 element Atomic radius / nm Melting point / ° C Boiling point / ° C Colour Fluorine ( F 2 ) 0 . 072 - 220 - 188 pale yellow Chlorine ( Cl 2 ) 0 . 099 - 101 - 35 green / yellow Bromine ( Br 2 ) 0 . 114 - 7 59 orange / brown Iodine ( I 2 ) 0 . 133 114 184 grey / black solid, purple vapour

The sub 0 ° C melting and boiling points of fluorine and chlorine mean that these two are gases at 20 ° C . A sub 0 ° C melting point and a boiling point greater than 20 ° C means that bromine is liquid at 20 ° C . High melting and boiling points of iodine mean that iodine is a solid at 20 ° C .
