Which statement is correct regarding the trends in properties of the Group 7 (17) elements and their compounds down the group from fluorine to iodine?
The electronegativity of the halogen atoms increases down the group as nuclear charge increases.
The boiling point of the halogens increases down the group because the strength of the covalent bonds within the diatomic molecules increases.
The solubility of the silver halides, AgX\text{AgX}AgX, in aqueous ammonia decreases down the group.
The reducing ability of the halide ions, X−\text{X}^-X−, decreases down the group as the ionic radius increases.
