What is selenium standard state?
In its standard state, selenium exists as a grey, metallically lustrous solid with a crystalline structure. It is a nonmetal with properties that are intermediate between sulfur and tellurium. Selenium is typically found in nature in its elemental form or in various minerals.
Which one is more brittle selenium or sodium?
Selenium is generally more brittle than sodium. While sodium is a soft, malleable metal that can be easily cut with a knife, selenium, a nonmetal, tends to be more rigid and can break or fracture under stress. The brittleness of selenium makes it more prone to cracking compared to the ductile nature of sodium.
Why was selenium not identified as an element until 1818?
Selenium was not identified as an element until 1818 because it is a trace element found in a limited number of ores and does not occur in its pure form in nature. Its discovery was also hindered by its similarity to tellurium, another element with similar chemical properties, which made it difficult to separate them. Additionally, advancements in analytical chemistry techniques were necessary for its isolation and identification.
What is SeO3?
SeO3, or selenium trioxide, is a chemical compound consisting of selenium and oxygen. It is a colorless, volatile liquid that is highly reactive and serves as a powerful oxidizing agent. Selenium trioxide is primarily used in the production of selenium compounds and in various chemical synthesis processes. Due to its toxicity and corrosive nature, it must be handled with care in laboratory and industrial settings.
Does bromine occur as a liquid in nature?
Bromine is a liquid but doesn't occur in nature as a free element.
Where selenium found?
Selenium is a nonmetallic element with an atomic number of 34 and an atomic weight of 78.96. Its chemical symbol is Se. Selenium is most commonly found in nature in its inorganic form, sodium selenite. An organic form of selenium, selenomethionine, is found in foods

Did halogens frequently occur in nature as free elements?
Yes, the halogens did occur in nature as free elements.
Where can you find selenium?

What is the correct name for SeF6?
This compound is called selenium hexafluoride.
Forces or things that occur in nature?
Gravity, electromagnetism, friction, and wind are forces that occur in nature. Earthquakes, volcanic eruptions, lightning, and tornadoes are natural phenomena that occur in nature.
