WebMelting point The temperature at which the solid–liquid phase change occurs. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Density (g cm −3) WebTechnetium is a silvery-gray metal that tarnishes slowly in moist air. The common oxidation states of technetium are +7, +5, and +4. Under oxidizing conditions technetium (VII) will exist as the pertechnetate ion, TcO 4-. The chemistry of technetium is said to be similar to that of rhenium. graavisärki
