Appearance | Sulfur is a yellow, crystalline solid at room temperature. |
Odor | Sulfur has a distinctive, strong odor that is often described as being similar to rotten eggs. |
Melting point | The melting point of sulfur is 115.21 °C (239.38 °F). |
Boiling point | The boiling point of sulfur is 444.6 °C (832.3 °F). |
Density | The density of sulfur is 2.07 g/cm3. |
Solubility | Sulfur is insoluble in water, but it is soluble in organic solvents like carbon disulfide and benzene. |
State of matter | Sulfur is a solid at room temperature and pressure, but it can be melted or vaporized under certain conditions. |
Crystal structure | Sulfur has a rhombic crystal structure at room temperature, but it can also exist in other crystal structures at different temperatures and pressures. |
Hardness | Sulfur has a hardness of 1.5 on the Mohs scale, which means it is a relatively soft mineral. |
Conductivity | Sulfur is a poor conductor of electricity and heat. |
Color | Sulfur is typically yellow in color, but it can also appear in shades of brown, red, or black depending on the impurities present. |
Molecular weight | The molecular weight of sulfur is 32.06 g/mol. |
Viscosity | Sulfur has a low viscosity, which means it flows relatively easily. |
Flammability | Sulfur is flammable and can ignite when exposed to a flame or spark. |
Reactivity | Sulfur can react with many other elements and compounds, including metals, acids, and halogens. |
Toxicity | Sulfur is not highly toxic, but it can cause irritation or damage to the skin, eyes, and respiratory system if ingested or inhaled in large quantities. |
Magnetic properties | Sulfur is diamagnetic, which means it is not attracted to a magnet. |
Thermal conductivity | Sulfur has a low thermal conductivity, which means it does not transfer heat well. |
Stability | Sulfur is a relatively stable element under normal conditions, but it can undergo oxidation or reduction reactions in certain environments. |
Optical properties | Sulfur is opaque to visible light and has a relatively low refractive index. |
Radioactivity | Sulfur has no radioactive isotopes, so it is not radioactive. |
Corrosivity | Sulfur can corrode certain metals, especially in the presence of water or other corrosive agents. |
Hygroscopicity | Sulfur can absorb moisture from the air and become damp or sticky. |
Tensile strength | Sulfur is relatively brittle and has a low tensile strength, meaning it is not well-suited for use in structural applications. |

It’s worth noting that some of these properties can vary depending on the specific form of sulfur and the conditions under which it is present.
For example, sulfur can exist in different allotropes with different physical properties, and its melting and boiling points can change depending on the pressure and atmospheric conditions.
