S Block Elements One Shot

Configuration Of S And P Block Elements

In s - and p -block elements the OS . changes in units, but in transition elements it changes it chnages in units of one. Explain ?

How many s -block elements are known ?

Why are the 's-' and 'p-' blocks elements called representative elements?

In s- block elements, the differentiating electron enters the ________orbital.

Atomic numbers of few elements as 56,57,72,89,49,38,46 among then No of S-block elements = X No of P-block elements =Y No of d-block elements =Z Then X +Z - Y value is

Atoms of d-block elements in a given period are smaller than those of s-block elements but bigger than those of p-block elements. However, the variation within a given series is quite small because
