Consider the following property of Lithium:1. It is much harder and lighter than the other alkali metal.2. It form stable complex compound.3. It react with water very slowly.4. It is less reactive than other alkali metal.Which of the above statement is/are correct?
Correct answer: D. 1,2,3 and 4
- A. 1 Only
- B. 2 Only
- C. 3 and 4 only
- D. 1,2,3 and 4
Explanation
Lithium exhibits unique properties among alkali metals. It reacts slowly with water, forms stable complex compounds, is harder and lighter than other alkali metals, and is less reactive overall. This makes Option D the correct choice as all statements about Lithium are accurate. Options A, B, and C are incorrect as they do not acknowledge all the correct properties of Lithium.

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.
