The question is incomplete but i will try to answer it to the best of my ability.
An element of configuration 2.8.6 is in group 16. This element will form a divalent anion Z^2-
Z is a nonmetal which combines with metals to form ionic bonds. Z can also react with other non metals to form covalent compounds.
Z is expected to have high electronegativity and electron affinity since it is a nonmetal of group 16.
The oxides of Z will dissolve in water to yield acidic solutions.
