Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
We are given four chemical symbols and need to identify which element belongs to the oxygen family (Group 16 elements, also known as chalcogens) in the periodic table.
Step 2: Detailed Explanation:
Let's analyze the periodic table group placement for each option:
Ba (Barium): Belongs to Group 2, which comprises the alkaline earth metals.
Se (Selenium): Belongs to Group 16, directly underneath sulfur. The vertical sequence for Group 16 is Oxygen (O), Sulfur (S), Selenium (Se), Tellurium (Te), and Polonium (Po). Therefore, it belongs to the oxygen family.
Rb (Rubidium): Belongs to Group 1, which represents the alkali metals.
Ca (Calcium): Belongs to Group 2, which also represents the alkaline earth metals.
Step 3: Final Answer:
Selenium (Se) is the element that belongs to the oxygen family, matching option (B).
