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)
Naming a complex anion - 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 - Is it tennessINE because it has 117 electrons or because . . . The element's name ends with -ine instead of -ium probably because it is in group 17 all of whose elements are non-metals as names of most metals preferentially ends with a - ium It's not possible as of yet to determine its experimental properties given that only six atoms of Tennessine have been created
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)
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
Why do we use helium in balloons? - Chemistry Stack Exchange While I was looking at the periodic table today, I realised that there were gases that were much lighter than helium such as hydrogen If hydrogen is lighter than helium, why do we insist on using
How can I find out a substances name from its structural formula? That's betanin, from which beets derive much of their deep purple color, and which may have neuro-protective (Ref 1) features The following is the structure retrieved from the wikipedia (on 2019-10-5), which closely matches that in the mosaic: I used the editor available on the Sigma-Aldritch website to generate a structure and submit a search: The program identified betanin as the top hit
What is the pKa of the hydronium, or oxonium, ion (H3O+)? There is the problem of having 55 56 molar hydronium re its counterion being included Consider water azeotropes of strong acids not by wt-% but by mole ratio Is there anything interesting to be had there?
What is the pKaH of pyrrole? - Chemistry Stack Exchange Op's question is what is the correct $\mathrm {p}K_\mathrm {a}\ce {H}$ value of pyrrole Thus, I'm not going to elaborate OP's findings, but would try to give a reasonable answer to the question The most reasonable answer I found for $\mathrm {p}K_\mathrm {a}\ce {H}$ value for the pyrrole is $0 4$ (for the novices, this is the $\mathrm {p}K_\mathrm {a}$ of the conjugate acid of pyrrole) It
