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 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.
