Plutonium is a man-made actinide element that is produced in nuclear reactors and nuclear weapons. It is used as a fuel in nuclear reactors and in the production of nuclear weapons.
as a consequence of actinide contraction the radius of the metal atom decreases as the 5f electrons of the actinides are poorly shielded. (Due to this poor shielding it is more strongly attracted by the nuclear charge resulting in decreased radius)
Fermium is a member of the actinides group.
Hydrogen is a none metal element. atomic number of it is 1.
Actinide contraction refers to the decrease in atomic and ionic radii of actinide elements as you move across the actinide series. This phenomenon is due to the poor shielding of the nuclear charge by inner electrons, leading to increased nuclear attraction on outer electrons. The consequences of actinide contraction include increased stability of higher oxidation states and differences in chemical properties compared to the lanthanides.
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
Radon is not an actinide, it is a noble gas.
Plutonium is an actinide
Manmade actually.
Manmade
No uranium is an actinide and is very hard especially depleted uranium
manmade
The lowest atomic number actinide is actinium, with the atomic number 89.
Manmade God ended in 2004.
Manmade God was created in 2001.

Einsteinium is a trivalent actinide metal.
