Actinides
Most of the actinides are transuranium (man made).
Elements 90-109 are considered actinides.
All of the elements are radioactive.
Actinides have applications in nuclear research, medicine, and industry
All of them have a silvery or silvery white luster in their metallic forms.
All actinides have the ability to undergo nuclear reactions.
They are very hazardous to handle.
The interaction of radioactive actinides with different types of phosphors will produce pulses of light.
Much of what is known about actinides comes from the comparison of properties to lanthanides.
Actinides combine directly with most nonmetals.
Uses:
Thorium is used as an alloying agent.
Americium is found in metal detectors.
Both uranium and plutonium have been used in atomic weapons for their explosive power and currently are being employed in nuclear plants for the production of electrical power.
