Metals vs. Metalloids: What's the Difference?
Metals are elements with high electrical conductivity, malleability, and ductility, while metalloids possess intermediate properties of metals and nonmetals, exhibiting mixed conductivity and appearance.
Metals, forming the majority of the periodic table, and metalloids, scattered sparingly amidst them, exhibit contrasting characteristics despite their adjacency on the periodic chart. Metals commonly boast properties such as high conductivity, malleability, and shininess, while metalloids tend to straddle the line, showcasing a mix of metallic and nonmetallic characteristics. Although metalloids might share some visual aspects with metals, their physical and chemical divergences are rather notable.
Metals, in a generalized sense, are identified for their capacity to conduct electricity and heat with remarkable proficiency, while metalloids navigate a middle ground in this regard. Metalloids might conduct electricity, but not as efficiently as metals, often being semiconductors, pivotal in the electronics industry. Metals are generally ductile and malleable, while metalloids don’t always exhibit these traits, frequently bristling against the easy categorization that metals might slide into.
In an electrochemical context, metals and metalloids do not stand on identical grounds. Metals tend to lose electrons, becoming cations, while metalloids might either lose or gain electrons, thus showcasing their ambivalent nature that metals do not characteristically demonstrate. The chemical behavior of metals is typically predictable, while metalloids defy expectation, moving in a direction that strays from the streamlined path of metals.
Metals, solid, robust, and often dense, contrast against metalloids which might present a divergent physical appearance. Whereas metals mirror each other with their shiny, often silver-gray appearance, metalloids might vary in color and lack the uniform luster that is quintessentially metallic. Metalloids, sitting on the fence between metals and nonmetals, tease aspects from both categories, forming a unique classification that metals do not embody.
While metals and metalloids may neighbor each other on the periodic table, their applications in industries and sciences diverge with noticeable significance. Metals find ubiquitous application in construction, transportation, and utensils owing to their strength and durability, while metalloids often find a niche in the technological and electronic sectors, leveraging their semiconductor properties which metals cannot inherently offer. Both critical to varying industries, metals and metalloids delineate their importance through their disparate properties and applications.

Typical metals form salts with nonmetals, basic oxides with oxygen, and alloys with one another.
A nonmetallic element, such as arsenic, that has some of the chemical properties of a metal. Most metalloids behave as semiconductors.
A nonmetallic element, such as carbon, that can form an alloy with metals.
Relating to or having the properties of a metalloid.
Having the appearance of a metal.
