The Correct Option is B

Xenon belongs to noble gases which are considered to be very unreactive. In xenon atom, the ionisation potential of

Xe

to lose one electron was found to be nearly equivalent that of

O _{2} \rightarrow O _{2}{ }^{+}+ e ^{-}

. Also, due to the presence of empty

5 d

-orbitals, electrons can be excited and higher valency of xenon can be produced.

e . g . XeF _{2}, XeF _{4}, XeF _{6}

etc.

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.
