Why do the names of most chemical elements end with -um or -ium? The -ium suffix is a Latin suffix which forms abstract nouns, thus it is used to form chemical elements' name from its naming origin, such as minerals (calcium from calx) or person names (gadolinium)
nomenclature - Is it tennessINE because it has 117 electrons or because . . . When I first heard that name, I thought it was a mistake All the other synthetic elements ended in -ium - think plutonium or americium Oak Ridge nuclear engineer Julie Ezold understands my confusion JULIE EZOLD: We all thought it was going to be that way as well But remember - the periodic table has rules
Did Berzelius unify the names of chemical elements using the Latin . . . For linguistic consistency, the names of all new elements should end in “-ium” The common, and IUPAC recognised, names of gold and gilver both have old Germanic origins and are recognised as official names because of their widespread usage
What is a sigma complex? - Chemistry Stack Exchange 18 According to Wikipedia, "sigma complex" refers to an arenium ion The suffix "-ium" denotes a positively charged ion So, it is correct to call the resonance structures in the below picture depictions of a sigma complex? It's distinctly anionic rather than cationic
Naming a coordination compound - Chemistry Stack Exchange The rest of the metals simply have -ate added to the end (cobaltate, nickelate, zincate, osmate, cadmate, platinate, mercurate, etc Note that the -ate tends to replace -um or -ium, if present)
nomenclature - Are the names for chemical elements the same in both . . . Yes, the placeholder names all end in -ium, but that section isn't about placeholder names, it's about actual names And for actual names, it's the metallic elements that end in -ium (that qualifier is seen elsewhere in that paper, not sure why they left it out there)
Why do all radioactive decay series terminate at lead? Thorium series: Uranium series: Actinium series: Why do all the radioactive decay series terminate at lead isotope? Why not hydrogen? (All pictures were taken from Wikipedia )
Why do people often capitalize element names? According to IUPAC rules, names of chemical elements should not be capitalized See Wikipedia’s take on the issue: According to IUPAC, chemical elements are not proper nouns in English; consequen
