A ionic

Explanation:

Group 1A has the lowest electronegativity of any family of elements.
Group 7A has the highest electronegative of any family of elements

The difference in electronegativity of 1.7 makes a bond ionic. Because of the difference in electronegativity between group 1A and group 7A the bonds formed between them are ionic.
