Groups of college students pursue the study of chemical compounds with similar reactivity. if they wish to do an in-depth background study on periodic trends, they should most likely a) consult only their chemistry professors. b) rely exclusively on each other’s background knowledge. c) consult chemistry professors, chemistry textbooks, and scientific journals. d) consult chemistry professors and further study through scientific-fiction movies.

The correct answer will be option-C.

Explanation:

A scientific investigation on a new scientific idea begins by following the procedural steps of the scientific method.

A scientific method includes many steps, one of which is doing background research to understand the idea of a scientific topic. The relevant study material to do background research should be a scientific journal as they include articles reviewed by the peer-review which tests the validity of the hypothesis.

In the given question, to do new research, students must follow the scientific books and scientific journals to do background research and should consult their chemistry professor who suggests ideas to perform error-free experiments and further guidance.

Thus, Option-C is the correct answer.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
