Account for the following :
(i) Oxygen does not show an oxidation state of + 4 and + 6 like sulfur .
(ii) `NO_2` readily forms a dimer.
(iii) Fluorine always exhibits and oxidation state of -1 only in its compunds

Sodium ordinarily does not show an oxidation state of +2 , because of its

Give reasons for the following : Fluorine shows an oxidation state of -1 only.

Which of the following halogen always show only one oxidation state -

Account for the following: Tendency to show -2 oxidation state diminishes from sulfur to polonium in group 16.

In which of the compounds oxygen does not exhibit oxidation state (-2)?

Why sulphur is able to show oxidation state of +4 and +6 with fluroine and oxygen ?

Which one of the following elements does exhibit +1 oxidation state as well ? AI, B, Ca, TI, Be.

Give reason for the following : (i) Mn shows the highest oxidation state of +7 with oxygen but with fluorine, it shows the highest oxidation state of +4 (ii) Transition metals show variable oxidation states. (iii) Actinoids show irregularities in their electronic configurations.

Account for the following: The valency of oxygen is generally 2, whereas sulfur shows valency of 2, 4 and 6.

Account for the following : Two S - O bond lengths in SO_(2) are equal. (ii) Fluorine shows only - 1 oxidation state in its compounds.
