No, elemental sulfur (S) is not acidic, mainly because it is insoluble with water.
However both sulfur oxides: SO2 and SO3 are acid forming oxides (weak and strong respectively), like most nonmetal oxides are in nature.

Sulfur itself is not acidic. However, sulfur compounds such as sulfuric acid are highly acidic.
NO!!!
It is an element.
However, when combined with oxygen it then forms acidic gases SO2, and SO3 .
No, sulfur trioxide is not a base. It is an acidic oxide that reacts with water to form sulfuric acid.
Yes, when sulfur is burned, it produces sulfur dioxide, which is an acidic gas that can contribute to air pollution and acid rain.
Sulfur and oxygen are likely to form covalent bonds rather than ionic bonds due to their similar electronegativities. The compound formed would be acidic in nature because sulfur and oxygen can combine to form acidic oxides, such as sulfur dioxide and sulfur trioxide.
Sulfur dioxide dissolved in water forms sulfurous acid, making it an acidic solution.
Sulfur dioxide gas is acidic in nature. When dissolved in water, it forms sulfurous acid, which can lower the pH of a solution.
