The trihydrogen cation or protonated molecular hydrogen (IUPAC name: hydrogenonium ion) is a cation (positive ion) with formula H + 3, consisting of three hydrogen nuclei sharing two electrons. The trihydrogen cation is one of the most abundant ions in the universe.
Being unstable the molecule breaks up in under a millionth of a second. Its fleeting lifetime makes it rare, but it is quite commonly formed and destroyed in the universe thanks to the commonness of the trihydrogen cation. The infrared spectrum of H 3 due to vibration and rotation is very similar to that of the ion, H + 3. In the early universe ...
The two electrons go into the bonding orbital, resulting in a net bonding effect and constituting a chemical bond among all three atoms. In many common bonds of this type, the bonding orbital is shifted towards two of the three atoms instead of being spread equally among all three. Example molecules with 3c–2e bonds are the trihydrogen cation ...
A hydrogen molecular ion cluster or hydrogen cluster ion is a positively charged cluster of hydrogen molecules. The hydrogen molecular ion (H + 2) and trihydrogen ion (H + 3) are well defined molecular species. However hydrogen also forms singly charged clusters (H + n) with n up to 120.
The concentration of hydrogen ions and pH are inversely proportional; in an aqueous solution, an increased concentration of hydrogen ions yields a low pH, and subsequently, an acidic product. By definition, an acid is an ion or molecule that can donate a proton, and when introduced to a solution it will react with water molecules (H 2 O) to ...
On e-commerce platforms like Etsy, TikTok Shop, eBay and Redbubble, sellers are hawking merchandise featuring designs inspired by the fatal shooting of UnitedHealthcare CEO Brian Thompson.
ABC's "The View" was home to several contentious moments and prominent Democratic interviews in 2024, including a key moment of VP Kamala Harris' campaign.
Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...
