Question:

Catenation i.e., linking of similar atoms depends on size and electronic configuration of atoms. The tendency of catenation in Group $14$ elements follows the order

Updated On: Jul 6, 2022
  • $C > Si > Ge > Sn $
  • $C > > Si > Ge \approx Sn$
  • $Si > C > Sn > Ge $
  • $Ge > Sn > Si > C$

The Correct Option is B

Solution and Explanation

As we go down the group, the atomic size increases and electronegativity decreases and thereby, tendency to show catenation decreases. Hence, the order of catenation is $C > > Si > Ge \approx Sn$.

P-Block Elements

  • 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.

P block elements consist of:
