An element with atomic number 82 belongs to group
Correct answer: C. 14
- A. 16
- B. 12
- C. 14
- D. 2
Explanation
The element with atomic number 82 is lead (Pb), which is located in Group 14 of the periodic table. Group 14 is known for housing elements that include carbon (C), silicon (Si), and lead (Pb). The other options represent different groups: Group 16 contains chalcogens like oxygen, Group 12 consists of transition metals like zinc, and Group 2 comprises alkaline earth metals like magnesium, none of which match the characteristics of lead.

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.
