All identified mercury compounds show amongst two good oxidation states: I and II. Experiments have did not unequivocally exhibit any better oxidation states: both of those the claimed 1976 electrosynthesis of an unstable Hg(III) species and 2007 cryogenic isolation of HgF4 have disputed interpretations and stay hard (Otherwise difficult) to breed.[sixty three]
[12] It stays in use in scientific investigate programs As well as in amalgam for dental restoration in certain locales. It is also even now Employed in fluorescent lighting, Even though the amount of mercury used is currently scaled-down.
