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.
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.

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.

No. It is not radioactive.
A fresh surface of plutonium is silvery, metallic.
Plutonium is normally solid and metallic.

As a metal plutonium has metallic bonds. Salts of Pu have ionic bonds.
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')
