Question

Which of the following is not a chalcogen?

• A. $O$
• B. $S$
• C. $Se$
• D. $P$

Answer 1

Answer: (D)

$P$

The chalcogens are the elements of group 16 in the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po).

So $P$ is not present in chalcogen family.

Hence option D is correct.
