Answer

Brief Explanations:

Elements in the same group of the periodic table have the same number of valence electrons. Bismuth and nitrogen both have 5 valence electrons, making them likely to be in the same group. Atomic mass, year of isolation, and name - suffix are not reliable indicators for group - membership.

Answer:

D. bismuth and nitrogen, because they have the same number of valence electrons
