Metallic character of alkaline earth metals ------down the groups.
Correct answer: C. increases
- A. decreases
- B. gradually increases then decreases
- C. increases
- D. remains same
Explanation
The metallic character of alkaline earth metals increases down the group.As you move down Group 2 in the periodic table, elements like beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra) have a decreasing ionization energy, making it easier to lose electrons and an increasing atomic size, which leads to weaker attraction between the nucleus and outer electrons.These trends make it easier for atoms to donate electrons and exhibit metallic properties, such as conductivity and reactivity, as you go down the group.

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.
