Consider the elements:
`Cs, Ne, I` and `F`
a. Identify the element that exhibits only negative oxidation state.
b. Identify the element that exhibits only positive oxidation state.
c. Identify the element that exhibits both positive and negative oxidation states.
d. Identify the element which exhibits neither the negative nor does the positive oxidation state.

Text Solution

Verified by Experts

(a) F fluorine beig the most elctrogative element show only a ve oxidation state of -1 (b) Cs alkali metals because of the presence of a singel eletocn in the valence shell exhibit an oxidation state of +1
(c ) 1 because of th present of seven electrons in the valence shell i shows an oxidation state of -1 or an oxidation state of +1 and because of the presence of d orbitals it also exhibits +ve oxidation states of +3 +5 and +7
(d) ne it is insert gas and hence it neither exhibits -ve nor +e oxidation states
