Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Electronic configuration determines the position of an element in the periodic table.
Step 2: Analysis
Atomic number 53 corresponds to Iodine (I). Electronic configuration: $[Kr] 4d^{10} 5s^{2} 5p^{5}$.
Step 3: Classification
Elements with $ns^2 np^5$ valence configuration are Group 17 elements, known as Halogens.
Step 4: Conclusion
Hence, the element belongs to the halogen family.
