Solution

All the elements of the halogen family exhibit -1 oxidation state. However, elements such as chlorine, bromine, and iodine also show +1, +3, +5 and +7 state.

in the positive oxidation number of Xe is perxenate ion $X e O_{6}^{4 -}$ is eight.

Hence only O , Cl, Br, I and Xe shows positive oxidation state .

only 5 atom are show positive oxidation state
