After some nuclear reactions, americium and curium; see for more details at: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
It's called "Mendelevium"
Americium
Platinum is a metallic, solid, radioactive chemical element; now it is considered a natural element. Plutonium is a member of the actinides group.
Plutonium has a metallic appearance.
Uranium or plutonium
As a metal plutonium has metallic bonds. Salts of Pu have ionic bonds.
The element with chemical symbol Np is Neptunium. Neptunium is a radioactive Lanthanide and is part of the unofficial Promethium family. It has 93 electrons in 7 shells and is next to Uranium and Plutonium.
Platinum is a metallic, solid, radioactive chemical element; now it is considered a natural element. Plutonium is a member of the actinides group.
nobelium is a radioactive element produced artificially from curium. Curium is a silvery white metallic radioactive element artificially produced from plutonium. Plutonium is a toxic radioactive metallic element used in nuclear reactors and weapons.
Plutonium has a metallic appearance.
The fresh surface of plutonium has a silvery metallic appearance.
The fresh surface of plutonium is metallic, silvery.
A fresh surface of plutonium is silvery, metallic.
No. It is not radioactive.
A fresh surface of plutonium is silvery, metallic.
Plutonium is normally solid and metallic.
Uranium or plutonium
Yes, Americium is a synthetic element that has the symbol Am and atomic number 95.As radioactive metallic element, americium is an actinide that was obtained in 1944 by Glenn T. Seaborg who was bombarding plutonium with neutrons. (And, of course: Glenn was 'man')
As a metal plutonium has metallic bonds. Salts of Pu have ionic bonds.
