What is the identification of sulfur?
What is the identification of sulfur?
Elemental sulfur is a bright yellow, crystalline solid at room temperature. It occurs in the form of sulfides, sulfates, and elemental sulfur. The bright yellow or orangish color of this mineral makes the mineral easy to identify.
How was sulfur created?
Native sulfur is formed when hydrocarbons come in contact with sulfate minerals in presence of liquid water. The prevailing model for native sulfur formation in such settings is that sulfide produced by sulfate-reducing bacteria is oxidized to zero-valent sulfur in presence of molecular oxygen (O2).
What is sulfurs chemical formula?
Sulfur or sulphur is the chemical element with atomic number 16, represented by the symbol S. At normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8.
What is the Diaphaneity of sulfur?

What is the texture of sulfur?
brittle solid
Characteristics: Sulfur is a soft, pale yellow, odorless, brittle solid.
Who discovered sulfur?
Antoine Lavoisier recognized it as an element in 1777, although it was considered by some to be a compound of hydrogen and oxygen; its elemental nature was established by the French chemists Joseph Gay-Lussac and Louis Thenard.
What is sulfur made from?
Historically and in literature sulfur is also called brimstone, which means “burning stone”. Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum….

Is sulfur a S8?
Sulfur is a chemical element that is present in all living tissues. The most commonly used form of pharmaceutical sulfur is Octasulfur (S8). After calcium and phosphorus, it is the third most abundant mineral in the human body. Sulfur is also found in garlic, onions and broccoli.
How did Antoine Lavoisier discover sulfur?
In 1777 Lavoisier correctly identified sulfur as an element. He had carried out extensive experiments involving this substance and observed that it could not be broken down into any simpler substances.
What are the characteristics of sulfur?
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What is special about sulfur?
Sulfur is essential to all living things. It is taken up as sulfate from the soil (or seawater) by plants and algae. It is used to make two of the essential amino acids needed to make proteins. It is also needed in some co-enzymes.
