Metals vs. Metalloids: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Metals are elements with high electrical conductivity, luster, and malleability, while metalloids exhibit properties between metals and nonmetals.
Key Differences
Metals are typically solid at room temperature (except mercury), known for their shiny luster, high electrical and thermal conductivity, and malleability. Metalloids, in contrast, have a mixture of metallic and nonmetallic properties, making them less conductive than metals and often more brittle.

Metals can easily lose electrons, making them good conductors of electricity. They are usually ductile, allowing them to be drawn into wires. Metalloids, however, have a more variable ability to conduct electricity, often changing with temperature, and they are less malleable than metals.

The reactivity of metals varies widely; some, like sodium, react violently with water, while others, like gold, are very unreactive. Metalloids often have intermediate reactivity, being neither as reactive as the most active metals nor as inert as the most inactive metals.

Metals are generally found on the left side and in the center of the periodic table and include groups such as alkali metals and transition metals. Metalloids are found along the metal-nonmetal dividing line in the periodic table, including elements like silicon and germanium.

In alloys, metals often form the primary component, imparting strength and electrical conductivity. Metalloids are used in smaller quantities in alloys and extensively in the semiconductor industry due to their variable electrical conductivity.

Metals
Any of a category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. Typical metals form salts with nonmetals, basic oxides with oxygen, and alloys with one another.
