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

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

Why S-block elements are called alkali metals.

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

Show that the relation R defined in the set A of all polygons are as R = {(P_1,P_2) : P_1, P_2 in A} P_1 and P_2 have same number of sides is an equivalence relation. What is the set of elements in A which are related to the rectangle having sides 4 and 5 cm?

In the modern Periodic table, which are the metals among the first ten elements?

Name three elements which are d-block elements but not transition elements.
