Which of the following is a chalcogen?
Correct answer: D. All are chalcogens
- A. Sulphur
- B. Selenium
- C. Tellurium
- D. All are chalcogens
Explanation
The correct answer is Option D: 'All are chalcogens.' Chalcogens are the elements in Group 16 of the periodic table. This group includes Oxygen, Sulphur, Selenium, Tellurium, and Polonium. Therefore, Options A, B, and C are all chalcogens, making Option D the correct choice. The other options are not incorrect but incomplete, as they only list individual chalcogens rather than acknowledging that all provided elements are chalcogens.

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.
