What is hydrogen role in nuclear fusion?

Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy. Hydrogen, heated to very high temperatures changes from a gas to a plasma in which the negatively-charged electrons are separated from the positively-charged atomic nuclei (ions).

I hope it's helpful!

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
