Not True Statement for Halogens:
All but fluorine show positive oxidation states
The statement that all but fluorine show positive oxidation states is not true for halogens. In fact, all halogens can exhibit negative oxidation states in addition to positive oxidation states.
Explanation:
Fluorine
- Fluorine is the most electronegative element and typically exhibits an oxidation state of -1 in compounds.
Chlorine
- Chlorine can exhibit oxidation states of -1, +1, +3, +5, +7 in various compounds.
Bromine
- Bromine can show oxidation states of -1, +1, +3, +5 in different compounds.
Iodine
- Iodine can display oxidation states of -1, +1, +3, +5, +7 in its compounds.
Astatine
- Astatine, the least known halogen, can also exhibit negative oxidation states in addition to positive oxidation states.
Therefore, the statement that all but fluorine show positive oxidation states is not true, as halogens can exhibit a range of oxidation states depending on the compounds they are present in.
