For atomic numbers given below , which pair of elements will have the same chemical properties ?
Correct answer: B. 3,11
- A. 13,22
- B. 3,11
- C. 4,24
- D. 2,4
Explanation
Elements belonging to the same group have the same chemical properties. The 13th element in the periodic table is aluminum and 22nd is titanium belonging to different groups and periods.Hence they have different chemical properties. The 3rd element in the periodic table is lithium and the 11th is sodium, both belonging to 1st group/Alkali metals. Hence both have similar chemical properties. The 4th element in the periodic table is beryllium and the 24th is chromium, both belonging to different periods and groups.Hence they have different chemical properties. The 2nd element in the periodic table is helium and the 4th is beryllium, both belonging to different periods and groups.Hence they have different chemical properties.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
