Write one difference between transition elements and p-block elements with reference to variability of oxidation states.

उत्तर
Transition elements (with reference to variability of oxidation states)
- The transition elements shows variable oxidation states - due to incomplete filling of d
- orbitals in such a way that their oxidation states differ from each other by unity.
eg `V^{II},V^{III},V^{IV},V^V
p - block elements (with reference to variability of oxidation states)
- In p - block elements, we have a group oxidation state (which is sum of ns electrons and np electrons)
- down the group, the group oxidation no. decreasess by (+2) unit, due to inert pair effect.

An amorphous solid “A” burns in air to form a gas “B” which turns lime water milky. The gas is also produced as a by-product during roasting of sulphide ore. This gas decolourises acidified aqueous \[\ce{KMnO4}\] solution and reduces \[\ce{Fe^{3+}}\] to \[\ce{Fe^{2+}}\]. Identify the solid “A” and the gas “B” and write the reactions involved.
