Which of the following elements is most chemically similar to sulfur (S)?

A. Chlorine (CI)

C. Phosphorus (P)
D. Oxygen (O)

1 answer

The element most chemically similar to sulfur (S) is D. Oxygen (O).

Both sulfur and oxygen are in Group 16 of the periodic table, which means they share similar chemical properties. They both are nonmetals and have similar valence electron configurations. Phosphorus (P), while also in the same period as sulfur, does not share as many chemical similarities as oxygen does.
