actinide

This has a higher melting point than the actinide metals.

It is the first element of the actinide series.

The facility has a long history and extensive experience in handling actinide samples.

The actinide element group was unknown at the time.

To date the nature of the fuel (targets) for actinide transformation has not been chosen.

Neptunium-237 is the most mobile actinide in the deep geological repository environment.

It is the only technology that can destroy plutonium through its actinide recycle process.

The actinide series derives its name from the group 3 element actinium.

However, if fast reactors become available, they may be able to burn these, or almost any other actinide isotopes.

In 1945, he went against the advice of colleagues and proposed a significant change to Mendeleev's table: the actinide series.

It was the final and the heaviest element of the actinide series to be synthesized.

In physics and chemistry, it is the atomic number of mendelevium, an actinide.

The last actinide, lawrencium, also has one electron in the 6d subshell.

It is a radioactive metallic element and an actinide.

In principle, it should be possible to derive energy from the fission of any actinide nucleus.

The hydrated salts are also used for the extraction of actinide elements.

The term actinide was probably introduced by Victor Goldschmidt in 1937.

Ninety is the atomic number of thorium, an actinide.

Other oxidation states have been observed between +2 and +7, which is the widest range among the actinide elements.

In general, most actinide isotopes with an odd neutron number are fissile.

Such three-phase behavior is typical for the actinide sesquioxides.

A key need is application of actinide solid solutions in durable crystalline host phases.

Other promising actinide isotopes for nuclear power are thorium-232 and its product from the thorium fuel cycle, uranium-233.

The actinide series is the 15 chemical elements between actinium and lawrencium on the periodic table.
