Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Out of P, Na, S and Cl, chlorine does not react
directly but Na, P and S react with oxygen directly.
$ \, \, \, \, \, \, \, P_4 + 5O_2 \longrightarrow \, P_4O_{10} $
$ \, \, \, \, \, \, \, \, \, S + O_2 \longrightarrow \, SO_2 $
$ \, \, \, \, \, \, \, 4Na + O_2 \longrightarrow \, 2Na_2O $
directly but Na, P and S react with oxygen directly.
$ \, \, \, \, \, \, \, P_4 + 5O_2 \longrightarrow \, P_4O_{10} $
$ \, \, \, \, \, \, \, \, \, S + O_2 \longrightarrow \, SO_2 $
$ \, \, \, \, \, \, \, 4Na + O_2 \longrightarrow \, 2Na_2O $

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
