- $Si, SiO, SiO_{2}$
- $Pb,PbO,PbO_{2}$
- $C, CO, CO_{2}$
- $Sn, SnO, SnO_{ 2}$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$C$ forms two oxides $CO$ and $CO_{2}. CO$ is neutral and poisonous. $CO_{2}$ can be compressed to a refrigerant dry ice or solid $CO_{2}. SiO$ is unstable. $SnO$ and $PbO$ are amphoteric in nature.

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:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
