The word "malleable" means "bendable". Typically, we think of metals as being "malleable", but there are other materials in that category as well.

Metalloid
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!
Selenium is a brittle metalloid, not malleable like metals such as copper or gold. It can easily break, crumble, or be powdered under pressure instead of flattening or bending.
Metalloids, such as silicon and arsenic, are elements that have properties of both metals and nonmetals. They can conduct electricity like metals but are more brittle and less malleable.
Metalloids typically have properties that are intermediate between metals and nonmetals. They may share some properties with metals, such as malleability, but this can vary depending on the specific metalloid. For example, boron is a metalloid that is hard and brittle, unlike most metals which are malleable.
An element can also be identified as a metal, metalloid, or nonmetal based on its physical and chemical properties.
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.

Is molybdenum a metal nonmetal or a metalloid
Ununseptium, now known as tennessine (Ts), is a synthetic element with very few atoms produced, making its physical properties largely unknown. However, it is predicted to be a metalloid, and based on its position in the periodic table, it may exhibit some metallic characteristics. While definitive information on its malleability is lacking, it is generally expected that heavier elements in this category tend to be less malleable than their lighter counterparts. Thus, tennessine is likely to be non-malleable.
