Web12 apr. 2024 · Abstract. Mercury fluoride ions formed during the laser ablation of HgS (s) show the formation of six different cluster ion series viz., HgFn±, HgnFn-2±, HgnFn-1±, (HgF)n±, HgnFn+1±, and HgnFn+2±. Among the different ion series, the observation of high valent HgFn± (n±=3,4; n-=6-8) indicates the existence of corresponding molecules ... WebToxicity of the fluoride ion. In very tiny amounts, the fluoride ion, or the bifluoride ion HF 2 –, can pass through the human body, with no long term effects. This is why it is used in toothpaste.
