Give general electronic configuration of s- block elements.

what is the general electronic configuration of the elements off-block?

Explain the following observation: (i) Generally there is an increase in density of elements from titanium (Z=22) to copper (Z=29) in the first series of transition elements. (ii) Transition elements and their compounds are generally found to be catalysts in chemical reactions.

Describe The general characteristics of transition elements with special reference to the following: Catalyst

Generally Adsorption is an endothermic process. true/false
