- Planar
- Pentagonal bipyramid
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Shape of $X e F _{5}^{-} \rightarrow$
The Xe show $s p^{3} d^{3}$-hybridisation in $XeF _{5}^{-}$,
Thus, its geometry is Pentagonal-bipyramidal.
But, number of electron pair $=\frac{8+5+1}{2}=7$
Number of bond pair $=5^{2}$, number of lone pair $= 2$ .
A lot of electrons are present at axil position and all bonds are in same plane.
Hence, the shape is planar.

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
