Question

Group 1 elements have an average electronegativity of 0.84 (not including hydrogen). Group 17 elements have an average electronegativity of 2.99. These two groups often form bonds. Given this information, which kind of bond will they likely form (ionic or covalent), and what evidence supports your claim? If it is ionic, then include which group gives up its electron to the other group. In three to five sentences, explain your reasoning. (4 points)

Answer 1

Group I elements combine with group 17 elements to form ionic compounds such NaF, NaCl, etc. When the electronegativity DIFFERENCE is above about 1.7 the bond will be ionic. 2.99-0.84 >> 2.15 and ionic is the game. Group I elements give up electrons and gorup 17 elements accept them.
