WebHelium can form unstable compounds, known as excimers, with tungsten, iodine, fluorine, sulfur, and phosphorus when it is subjected to a glow discharge, to electron bombardment, or reduced to plasma by other means. The molecular compounds HeNe, HgHe 10, and WHe 2, and the molecular ions He + 2, He 2+ 2, HeH +, and HeD + have been created this way. WebMar 20, 2024 · Credit: Richard Kail Getty Images. Helium, the most noble of the noble gases, long thought to be completely inert and thus too standoffish to bond with other atoms, recently surprised chemists by ...

WebAnswer (1 of 4): Yes, all elements are able to have electons removed or added to cause them to become an ion (charged particle). Some will do this more easily than others. For … WebPredicting Monatomic Cation Charges . The atoms of the noble gases found in nature are uncombined with other atoms. The fact that the noble gas atoms do not gain, lose, or share their electrons suggests there must be something especially stable about having 2 (helium, He), 10 (neon, Ne), 18 (argon, Ar), 36 (krypton, Kr), 54 (xenon, Xe), or 86 (radon, Rn) …
WebHelium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least …
WebDec 17, 2014 · Noble gases usually do not form strong bonds between their atoms - it takes a fair amount of energy to dimerise them into excimers, but those are short-lived excited molecules. Thanks to excitation, shells of the atoms aren't closed and they react, but very quickly they lose energy and become separate atoms.
