Representative Elements and Their Characteristics

The video tutorial explains representative elements, which are elements with complete inner shells but incomplete outer shells, typically having less than eight electrons in the outermost shell. It covers the general configuration of these elements, highlighting that all S and P block elements are considered representative, except for noble gases. The tutorial also provides details on the electronic configuration of these elements, emphasizing the conditions for S and P block elements.
