.Which allotropic form of phosphorous is the most stable?
Correct answer: B. Black phosphorus is the most stable allotropic form of phosphorus.
- A. White phosphorus
- B. Black phosphorus is the most stable allotropic form of phosphorus.
- C. (c) Red phosphorus
- D. Violet phosphorus
Explanation
Reasons for stability:It has a layered structure with strong covalent bonds within each layer and weaker van der Waals forces between layers.This arrangement makes it less reactive and less prone to spontaneous combustion than other forms.It's also the most dense and least reactive form.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
