AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
The largest element among \(\mathrm{O}, \mathrm{Se}, \mathrm{S}, \mathrm{Te}\) is
- A \(\mathrm{S}\)
- B \(\mathrm{Se}\)
- C \(\mathrm{O}\)
- D \(\mathrm{Te}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Te}\)
Step-by-step Solution
Detailed explanation
As we move down the group in the periodic table, atomic size increases due to increase in principle quantum number. Oxygen, selenium, sulphur and tellurium are belongs to same group of the periodic table. Thus, the largest element among them is Te. Hence, the correct option is…
