We have to determine the type of element based on given description.
We have to choose between a metal, nonmetal and semimetal (metalloid).
Semimetals are the elements whose properties are intermediate between metals and nonmetals.
The physical properties of metals are:
State: Metals are usually solids at room temperature. An exception is mercury which is a liquid metal.
Luster: Metals are shiny in their appearance.
Conductivity: Metals are good conductors of heat and electricity due to the presence of free electrons.
Brittle/Ductile: Metals are ductile. They do not break or shatter.
