The melting point, boiling point, and density of nihonium are unknown but they are predicted to be greater than its group members. Nh element belongs to the boron group (13 groups) of periodic table so its properties are assumed to resemble thallium. It is assumed to be denser than the thallium.
WebTechnetium is in 1937 ontdekt door de Italianen Carlo Perrier en Emilio Segrè toen ze een molybdeen monster onderzochten. Het monster was in een cyclotron gebombardeerd met deuteriumkernen waardoor de isotoop technetium-97 (97Tc) ontstond. ‘Technetium" verwijst naar het Grieks ‘technetos’ wat kunstmatig betekent. Web3 jul. 2024 · Technetium is one of two elements with Z < 83 with no stable isotopes; all of technetium's isotopes are radioactive. (The other element is promethium.) Some isotopes are produced as uranium fission products. Properties: Technetium is a silvery-gray metal that tarnishes slowly in moist air. Common oxidation states are +7, +5, and +4.
WebTechnetium was the first artificially produced element. It was isolated by Carlo Perrier and Emilio Segrè in 1937.
