Unit 07 The p-Block Elements Revision Notes for Class 12 Chemistry

 

The general valence shell electronic configuration of p‐block elements ‐ ns2 np1–6
 
Group‐16thELEMENTS
 
KEY POINTS :‐
 
1. O, S, Se, Te and Po are present in G‐16th Their general electronic conf. of last shell is ns2,np4.
2. Atomic and ionic radii increases down the group while ionization enthalpy and electro-negativity decreases with increase in atomic number.
3. Because of compact nature of oxygen atom, it has less negative electron gain enthalpy than sulphur. However from sulphur onwards the value again becomes less negative up to polonium..
4. Members of group 16 show oxidation number ‐2, +2, +4 and +6. But oxygen shows +1 state in O2F2.
5. They make MO2 and MO3 type oxides. SO2 is reducing agent whereas TeO2 is oxidizing agent.
6. O2 is gas a n d other elements are solid.
7. O2 and S2 in vapour state are paramagnetic.

8. CONTACT PROCESS OF MANUFACTURE OF SULPHURIC ACID:‐
