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.
Does bromine occur as a liquid in nature?
Bromine is a liquid but doesn't occur in nature as a free element.
Did halogens frequently occur in nature as free elements?
Yes, the halogens did occur in nature as free elements.
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.
