Selenium is a chemical element that has the symbol Se and atomic number 34. It is a non-metal, which means it does not have properties of metals in its physical structure. Selenium’s most common oxidation state is +4. The word selenium comes from Greek words meaning “moon” or “moon goddess.” Selenium can be found in many different minerals, such as erythrite, bixbyite and bastnasite. Some people believe that selenium protects against cancer because it helps to regulate cell division rates and apoptosis (cell death).

Selenium is a chemical element that has the symbol Se and atomic number 34. It is a non-metal, which means it does not have properties of metals in its physical structure. Selenium’s most common oxidation state is +14
The word “selenium” comes from Greek words meaning “moon” or “moon goddess.” Selenium can be found in many different minerals, such as erythrite, bixbyite and bastnasite. Some people believe that selenium protects against cancer because it helps to regulate cell division rates and apoptosis (cell death).
Selenium has 34 valence electrons.
There are many selenium compounds, including selenourea, sodium selenite, thiosemicarbazide or TSCB for short. These compounds are often used in the form of a solution called “Perl’s Solution.” The most common oxidation state of selenium is +14. Selenoprotein P is an important protein that contains a methyl group with three atoms: one carbon atom and two hydrogen atoms – C H S per molecule. It also helps to regulate red blood cells during their maturation process by restricting how much hemoglobin they contain.
1. Selenium is a chemical element that has the symbol Se and atomic number 34
2. Selenium is a metalloid, meaning it’s in between metals and nonmetals on the periodic table
3. The word selenium comes from two Greek words – “selene” which means moon, and “einios,” which means transparent
4. Selenium can be found in many different types of rocks because it often contains metals such as copper or gold
5. There are no known uses for pure selenium except to make other chemicals like sulfur dioxide gas
6. Selenium can help protect cells against damage from free radicals because it binds with oxygen molecules to form an antioxidant called glutathione peroxide (GSHPx)
Selenium is a chemical element with the symbol Se and atomic number 34
It is a nonmetal in group 16 of the periodic table
It has an atomic weight of 78.96, but it can also be found as two different isotopes, selenium-75 and selenium-77
The metal resists oxidation in air at normal temperatures because it forms passivating oxide layers that protect the underlying metal from further oxidation
Selenium’s most common compounds are sulfide, telluride, selenides and oxysulfides
Selenium is used in many industrial processes including glassmaking and semiconductor fabrication due to its high refractive index
It also has applications as a photoconductor for digital photography or xerography where light exposure creates electricity through corona discharge photovoltaic cells (CPD) process
Selenium salts have been used since ancient times to cure ailments such as leprosy and psoriasis by topical application or ingestion
In addition to being an essential trace element for humans, it is required by some plants for growth
Trace amounts are necessary for life; however too much
The periodic table is a chart that organizes all of the elements in terms of their properties and behavior. Selenium, with an atomic number of 34, has a total of 18 valence electrons. It’s interesting to note that selenium is one of only three elements found on the periodic table that consists solely as nonmetallic crystals at room temperature.
Selenium is a chemical element with the symbol Se and atomic number 34. A rare, silvery-gray solid metal when it occurs in nature as the pure element, selenium is found naturally mostly combined with sulfur and phosphorus in various minerals; however these are not very common or important commercially. Commercially, refining of copper ores produces some selenium as a byproduct which can be made into high purity soluble salts such as sodium selenite for use as fertilizers. Selenium also has an interesting property that allows photocopying paper to turn white if exposed to light sources like ultraviolet light, creating what’s known as “xerographic effect.”
A basic introduction to the atomic number of selenium. Selenium is a chemical element with an atomic number of 34 and has four valence electrons. The table below displays some common compounds in which selenium can be found, as well as the type of compound it is bound to and its oxidation states, so you can get a better understanding for how many valence electrons this element has.

Molecules are made up of atoms, and an atom’s characteristics depend on the number of electrons it has. Selenium is no exception. This blog post will help you learn how many valence electrons selenium has and what that means for its chemical properties.
-Selenium is a chemical element and has an atomic number of 34. A valence electron is the outermost one in an atom or molecule, so Selenium has six valence electrons. It also reacts with water and oxygen to form selenates which are soluble salts. This means that it’s not only reactive but also soluble in water-based solutions.
