  2. Uses and Properties • The melting point of actinium is 1050o Celsius, 1323.15o Kelvin, and 1922o Fahrenheit. • It’s boiling point is 3200o Celsius, 3473.15o Kelvin, and 5792o Fahrenheit. • The density of Actinium is 10.07 grams per centimeter. • Actinium is a decay product of Uranium. • Actinium is a silvery rare earth with a cubic crystal structure. • Actinium’s chemical behavior is similar to rare earths, particularly lanthnum. • It is dangerously radioactive, 150X as radioactive as radium, making it a valuable source of neutrons and creates an glowing blue light. • Actinium is also usedto create thermoelectric power. • Other than this, actinium has no other uses, though actinium 225 os used in a certain medicine in a generator to create Bi-213 or alone for radio-immunotherapy. • Actinium has so very few uses because it is found only in trace amounts in uranium:1ton uranium = 1/10gram actinium.

  3. Where to Find Actinium • The name Actinium comes from the Greek word aktis or aktinos, meaning beam or ray. • It was discovered in 1899 by Andre’ Louis Debierne, a French chemist who separated it from pitchblende. • Natural Actinium is found in minimum amount in uranium ore as Actinium 227. • More often, it is made in milligram amounts in a nuclear reactor from Radium 226. • It glows in the dark in a bluish light.

  4. An Ode to Actinium It’s number eighty-nine, I hope you that don’t get too close, An element so fine. If ever your in a dark cave. 150X as radioactive as radium, And you see a blue light. Its actinium. In a place they say will fright, For it may be actinium. It’s a great source of neutrons. In it’s outer shell there’s two electrons. You’ll find a tenth of a gram of actinium, In one ton of uranium. A French chemist found it one day. It was given a name meaning beam or ray. With lanthanum it shares chemical behavior. It’s a rare earth with a cubic crystal structure.
