SELENIOUS Meaning and Definition

1. Selenious is an adjective used to describe elements or compounds containing the element selenium in its +4 oxidation state. It is derived from the chemical element selenium, which is a nonmetal found in group 16 of the periodic table. The term is primarily used in chemistry and refers to the presence of selenium in the chemical compound with an oxidation number of +4.

   In this state, the selenium atom has lost four electrons, resulting in a positive charge. This oxidation state gives selenious compounds their unique chemical properties and reactivity. Selenious compounds often exhibit characteristics such as being crystalline in nature, acidic in solution, and capable of forming various complex structures with other elements.

   Selenious compounds are widely used in various industries, including pharmaceuticals, photography, electronics, and catalysis. For example, selenious acid (H2SeO3) is an important compound used in the manufacturing of photographic emulsions, as a reducing agent in chemical reactions, and as a source of selenium in selenium-enriched foods and nutritional supplements.

   Additionally, the term selenious can also refer to the hypothetical acid selenious acid (H2SeO4), which contains selenium in its +6 oxidation state. However, this form of selenious acid is less commonly encountered compared to selenious acid in its +4 oxidation state.

2. Applied to an acid containing one equivalent of selenium and two of oxygen.

Etymology of SELENIOUS

The word "Selenious" comes from the element "selenium", which is a chemical element with the symbol Se and atomic number 34. The term "selenium" is derived from the Greek word "selene", meaning "moon". The connection between the element selenium and the moon lies in the fact that selenium was discovered spectroscopically by Swedish chemist Jöns Jacob Berzelius in 1817 when studying the chemical composition of a type of mineral called pyrite. The element was named "selenium" due to its resemblance to tellurium, another element with similar chemical properties, which comes from the Latin word "tellus" meaning "earth". So, "selenious" is derived from "selenium" to indicate compounds or substances that contain selenium.
