NCERT Solutions For Class 12 Chemistry Chapter 8 The d and f block elements The elements in which 4f and 5f are filled are called f block elements 59 95 |
Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18.
Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups.
Their valence shell electronic configuration is ns2np1-6(except for He).
The inner core of the electronic configuration may, however, differ.
What is p-block elements in chemistry class 12?
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells.
The p-subshell has three p-orbitals each of which can accommodate a maximum of two electrons, therefore there are six groups of p-block elements.
