NCERT Solutions for Class 11 Chemistry Chapter 11 P Block Elements

The p-Block Elements. Elements in which the last electron enters into any one of the three p-orbitals of their outermost shells are called p-block elements. There are six groups of p-block elements in the periodic table numbering from 13 to 18. It has all types of elements, such as metalloids, non-metal, and metal. Their chemical and physical properties are highly influenced by the difference between the inner core of their electronic configuration. The lighter elements of the group have a quite stable group oxidation state. The heavier elements have more stable lower oxidation states. The absence of d orbital in second-period elements has limited their maximum covalence to 4, while heavier ones can exceed this limit. An example of a typical non-metal is boron.
