ClO2 contains an odd electron and is paramagnetic. It reacts with ozone to give O2 and Cl2O6. 2ClO2 + 2O3 → Cl2O6 + 2O2 In Cl2O6, the average oxidation state of Cl is +6.
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
