Correct answer: B. Hydrogen gas
- A. Ions
- B. Hydrogen gas
- C. Water
- D. None of these
Explanation
The fire produced when alkali metals react with water is due to the ignition of the hydrogen gas released during the reaction. The reaction is highly exothermic, and the heat generated is sufficient to ignite the hydrogen gas.

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.
