Metals

Metals are materials that are typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity

Iron, steel, copper

most common examples of metals

Metalloids

Metalloids are elements that have properties intermediate between those of metals and nonmetals. They are typically semiconductors and can form alloys with metals; luster and solid at room temperature

Non-metals

Nonmetals are elements that typically lack metallic attributes. They are generally poor conductors of heat and electricity and can exist in solid, liquid, or gaseous forms at room temperature.

Non-metals, noble gases, halogens

the three subgroups of the 20 nonmetals on the table of elements
