8. An atom of element Z has the electronic configuration 2.8.6. Which
one of the following statements
about element Z is correct? *

See explanation

Explanation:

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.
