The Correct Option isC
Solution and Explanation
The electronic structure of azide ion $\left( N _{3}^{-}\right)$is a resonance hybrid of the following structure
Thus $N _{3}^{-}$ion has a linear symmetrical structure, since all atoms lie in a straight line. $N _{3}^{-}$is iso-electronic with $N _{2} O$ (22e $^{-}$)
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.
