"On going down a group in the P-block elements the non metallic character decreases" Explain.

Among s- and p- block element , which possess higher metalic character.?

Why S-block elements are called alkali metals.

In going down the group in nitrogen family classify the elements into different catagories.

Why the metallic character of alkali metals increase down the group?

Explain how defects in a metal block can be detected using ultrasound.

The E_(M^(2+)//M)^(Theta) for copper positive (+0.34V)It is only metal in the first series of transition elements showing this type of behevious. Explain.

In p-block elements the lower oxidation state is favoured by heavier elements where as in d-block elements this is just opposite why?
