114番元素フレロビウム(Fl)は現在その化学的性質が研究されている最も重い元素である。Flに関する最初の化学実験では、Flは貴ガス的な性質を持つ元素であると報告された。一方、2番目の研究では、Flは揮発性金属の性質を示すと報告された。より信頼性の高い結論を得るため、我々は更なる実験的研究を行い、二酸化ケイ素と金表面におけるFlの吸着挙動を調べた。その結果、Flは揮発性金属の水銀よりも高い揮発性と低い反応性を示し、一方、貴ガスのラドンよりは反応性が高いことを明らかにした。

Flerovium (Fl, element 114) is the heaviest element chemically studied so far. The first chemical experiment on Fl suggested that Fl is a noble-gas-like element, while the second studies suggested that Fl has a volatile-metal-like character. To obtain more reliable conclusion, we performed further experimental studies on Fl adsorption behavior on Si oxide and gold surfaces. The present results suggest that Fl is highly volatile and less reactive than the volatile metal, Hg, but has higher reactivity than the noble gas, Rn.
