Metalloid
Samarium is a metal. It is a rare earth element with properties characteristic of metals, such as being shiny, malleable, and having good electrical conductivity.
The word "malleable" means "bendable". Typically, we think of metals as being "malleable", but there are other materials in that category as well.
t that is a malleable, shiny solid, but doesn't conduct heat or electricity
A metal is malleable because aluminium, for example, can be compressed to a thin sheet and copper can be stretched to form a wire. On the other hand, a nonmetal isn't malleable. For example, carbon is extremely solid (it is a component of diamond). A metalloid, though, may be malleable or not depending on it's characteristics. Tin is a malleable substance (at some point) but silicon isn't... it's a rock!
It could be dull or shiny. It doesn't matter.
Argon is a gas !
Iodine is not shiny and malleable; it is a brittle solid at room temperature. It typically appears as dark gray or black crystals and does not exhibit the metallic luster characteristic of shiny metals. When subjected to pressure, iodine does not deform easily, which is why it cannot be classified as malleable.
The malleable, ductile, and shiny element is gold. It is a precious metal known for its beauty and valuable properties.
There several elements tend to be malleable and shiny. Some of them include potassium, sodium, lithium and many more.
Barium is not malleable or ductile as it is a brittle metal. It does exhibit some lustre, giving it a shiny appearance.
