WAS BEDEUTET RADIUM AUF ENGLISCH
Radium
Radium ist ein chemisches Element mit Symbol Ra und Atomnummer 88. Radium ist ein fast reinweißes Erdalkalimetall, aber es oxidiert leicht bei der Einwirkung von Luft und wird schwarz in Farbe. Alle Isotope des Radiums sind hochradioaktiv, wobei das stabilste Isotop Radium-226 ist, das eine Halbwertszeit von 1600 Jahren hat und in Radongas zerfällt. Wegen dieser Instabilität ist Radium lumineszierend und leuchtet blau. Radium, in Form von Radiumchlorid, wurde von Marie Curie und Pierre Curie im Jahre 1898 entdeckt. Sie extrahierten die Radiumverbindung aus Uraninit und veröffentlichten die Entdeckung an der französischen Akademie der Wissenschaften fünf Tage später. Radium wurde in seinem metallischen Zustand von Marie Curie und André-Louis Debierne durch die Elektrolyse von Radiumchlorid im Jahr 1910 isoliert. Seit seiner Entdeckung hat es Namen wie Radium A und Radium C2 zu mehreren Isotopen von anderen Elementen, die Zerfall Produkte von Radium sind -226 In der Natur wird Radium in Uranerzen in Spurenmengen gefunden, die so klein sind wie ein Siebtel eines Gramm pro Tonne Uraninit.
