P BLOCK ELEMETS
GROUP 16 TO 18
•The p-Block elements: Elements belonging to 
groups 13 to 18 of the periodic table are called p-
block elements.
•General electronic configuration of p-block 
elements: The p-block elements are characterized 
by the ns2np1-6 valence shell electronic configuration.
•Representative elements: Elements belonging to 
the s and p-blocks in the periodic table are called the 
representative elements or main group elements.
