Ductile describes material that can be pulled into a long wire.
Conductivity when an object transfers heat to another object.
Reactivity ease and speed with which an element combines, or reacts with other elements and compounds.

Metalloid has characteristics of both metals and non- metals.
Semiconductor conduct electricity under some conditions.
luster has characteristics of a metals and it mean to shine
dull has characteristics of a nonmetals and it mean no luster
