Identify the incorrect statement:
Correct answer: B. Alkaline earth metals except Mg react with dilute acid to give hydrogen gas
- A. Alkaline earth metals are less reactive than alkali metals
- B. Alkaline earth metals except Mg react with dilute acid to give hydrogen gas
- C. Alkaline earth metals are less basic than alkali metals
- D. Alkaline earth metals form ionic bonds with electronegative elements
Explanation
The correct answer is Option B. While most alkaline earth metals react with dilute acids to produce hydrogen gas, magnesium (Mg) also reacts with dilute acids, albeit less vigorously. Beryllium is the only alkaline earth metal that does not react with dilute acids due to the protective oxide layer it forms. Options A, C, and D are incorrect as they do not accurately represent the properties of alkaline earth metals.

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.
