Which of the following properties decreases in group 2 as we go down the group?
Correct answer: D. Ionization energy
- A. Shielding
- B. Atomic number
- C. proton number
- D. Ionization energy
Explanation
Ionization energy always decreases down the group because atomic size increases which weakens the force of attraction between the nucleus and electrons surrounding it. So, it becomes easy to remove electrons from the atom

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.
