Selenium is an element it was "made" in the nova of an exploding star several billion years ago.
Selenium is found on Earth in minerals such as pyrites where it partially replaces the sulfides. Native selenium is very rare. Most elemental selenium on the market comes as a byproduct of metal refining such as copper or the production of sulfuric acid.
Selenium sulfide can be made by reacting elemental selenium with sulfur, typically in the presence of a reducing agent. The reaction usually takes place at high temperatures. Alternatively, selenium sulfide can be prepared by reacting selenium dioxide with hydrogen sulfide gas under controlled conditions.
Selenium is a naturally occurring element. It is rarely found in nature as a pure element. It can be found in metal ores such as:
Berzelianite (Copper Selenide)
Clausthalite (Lead Selenide)
Eucairite (Silver Copper Selenide)
Hakite (Copper Mercury Silver Antimony Selenium Sulfide)
Klockmannite (Copper Selenide)
Palladseite (Palladium Selenide)
Penroseite (Nickel Selenide)
Selen-tellurium (Selenium Tellurium)
Tiemannite (Mercury Selenide)
Umangite (Copper Selenide
Pure selenium is usually produced as a by-product of refining copper sulfide for copper, where it is an impurity.
Some application of selenium are:
- vulcanization agent
- pigment for glass
- photocells
- additive in the process of manganese extraction by electrolysis
- component of alloys
it is used mainly for gases and heating oils, thus having the correct number of neutrons protons and electrons
i know a photophone device that was invented by alexander graham bell and it uses selenium to send signal at a distance

Which brand shampoo in India has selenium Sulfide?
Selsun is a popular brand of shampoo in India that contains selenium sulfide. It is commonly used to treat dandruff and other scalp conditions.
What is the geometry of the central atom in selenium sulfide?
The central atom in selenium sulfide has a bent molecular geometry due to the presence of two lone pairs on the selenium atom. This results in a distorted tetrahedral arrangement around the selenium atom.
Do you know If any of salicylic acid Nizoral selenium sulfide strip hair color if it is dyed?
Salicylic acid, Nizoral, and selenium sulfide are not known to strip hair color. Salicylic acid is commonly used for exfoliation in skincare products, Nizoral is an antifungal shampoo, and selenium sulfide is an antifungal agent also found in certain dandruff shampoos.

What is the chemical formula of chromium ( vi) sulfide?
The chemical formula of chromium(VI) sulfide is Cr2S3.
Is selenium sulfide good for hair lose?
Selenium sulfide is primarily used to treat dandruff and seborrheic dermatitis. It is not typically recommended for hair loss. If you are experiencing hair loss, it is best to consult with a healthcare professional to determine the underlying cause and appropriate treatment.
Where is selenium metal mined?
Selenium is primarily extracted as a byproduct of copper refining from sulfide ores in countries like the United States, Canada, Japan, and Russia. Additionally, selenium can also be extracted from lead, zinc, and nickel ores in various mining operations around the world.
