A chemical property of sulfur is that it does not react with water, and it burns in the air to produce sulfur dioxide. It also reacts with halogens and hot potassium hydroxide, which is a base. Chemical properties of elements include pH level, reactivity with water and heat combustion, while physical properties of elements are their boiling and melting points, appearance, color and density.
The difference between physical and chemical properties is that physical properties are characteristics of matter that can be measured or observed, while chemical properties are characteristics that become evident in a chemical reaction, such as sulfur's reaction in air.
Sulfur is a solid at room temperature and has the atomic weight of 32.065 grams per mole. Some physical properties of sulfur are its yellow color and its melting point of 239.38 degrees Fahrenheit.
