Trends of the Group 7 halogens



Trends:
„h All Group VII metals have 7 valence electrons (7 electrons in the highest energy level)
„h Atomic radius increases down the Group as successive 'electron shells' (energy levels) are filled
„h Electronegativity (the relative tendency shown by a bonded atom to attract electrons to it) decreases down the group, as the elements become more metallic in nature. (Typically, metals have low electronegativity, little ...
