Introduction To P-Block Elements

What are P-Block Elements?

P block elements are 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. Itโ€™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.

In this section, we will study the elements of P-block and their properties.

Do you know where P-block elements are in Periodic Table?

P-block Elements in Periodic Table

P block elements are nothing but the element in which the last electron enters the outermost p-subshell. P block starts from the 13th group and goes till 18th group in the periodic table. P block elements consist of

You must have seen that coal is used in villages to cook food. It is nothing but a P-block element i.e. carbon. Diamonds are used for making beautiful ornaments are also made up of carbon. Aluminium foil made up of aluminium is also made up of the p block element.

Characteristics of P-Block Elements

  • The general electronic configuration of p-block elements is ns2np1-6(except He). Whereas the inner core electronic configuration may differ. Just because of this difference the inner core, there are changes in both physical and chemical properties of the elements.
  • The oxidation state of elements in p โ€“ block is maximum when it is equal to a total number of valence electrons i.e. the sum of S and P electrons. One of the most interesting facts about the p-block elements is that it contains both non-metals and metalloids.

The first member of the p block elements differ from other elements in two major respects:

  1. First is the size and each and every property which depends upon the size.
  2. The second difference applies only to the p-block element which arises from the effects of d-orbitals in the valence shell of heavier elements.
