What is the common uses for actinium?
Actinium-225 is used in medicine to produce Bi-213 in a reusable generator or can be used alone as an agent for radio-immunotherapy. It is found only in traces in uranium ores as 227-Ac, an α and β emitter with a half-life of 21.773 years.
What is the reactivity of actinium?
Actinium itself glows in the dark and reacts with water to produce hydrogen gas. It also reacts with air and acids, but not bases. It is used in thermoelectric power sources and also used in neutron emitters.
What is the texture of actinium?
Actinium is a soft, silvery-white radioactive metal.
What is an interesting fact about actinium?
Word origin: The word actinium comes from the Greek aktis or aktinos, which means beam or ray. Discovery: Actinium has two independent discoverers: Andre Debierne, who found it in 1899, and F. Giesel, who discovered it in 1902. Actinium has 36 isotopes, none of which are stable.
Why does actinium glow?
Actinium is a silvery-white metal. It’s so intensely radioactive that visible samples of it glow a pale blue colour in the dark due to its radioactivity exciting the air around it.
Is actinium a actinide?
According to this definition, actinium, element 89, is the first member of the actinide series of elements, although it has no 5f electrons in its metallic, gaseous, or ionic forms.
What is actinium found in?
1899
Actinium/Discovered
Does actinium glow?
Actinium is a soft, silvery-white, radioactive, metallic element. Its estimated shear modulus is similar to that of lead. Owing to its strong radioactivity, actinium glows in the dark with a pale blue light, which originates from the surrounding air ionized by the emitted energetic particles.
What are some common uses for actinium?
The primary users of actinium are scientific researchers, who utilize it as a source of neutrons in nuclear research. An isotope of actinium can also be used to bombard bismuth to produce some interesting reactions, and this isotope is also used in nuclear medicine.
Is actinium used in bombs?
Actinium Bombs were a type of explosives used by the Confederacy of Independent Systems. Imperial Investigation teams suspect that these were the type of bombs used in the destruction of the planet Caamas .
Is actinium a man made element?
They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium . The actinides are most known for the elements uranium and plutonium which are used in nuclear reactors and nuclear bombs.
What does the name actinium mean?
Named from the Greek word meaning “ray”, actinium is a soft, silvery-white radioactive metal. It is the first metal of the actinide series, which includes the 15 elements from actinium to lawrencium .
