Study Notes

Key Chemistry Terms

Alloy: A combination of two or more elements, with at least one being a metal, enhancing properties like strength or corrosion resistance.
Ductile: Refers to materials, particularly metals, that can undergo significant deformation before rupture, demonstrating the ability to be drawn into thin wires.
Group: A vertical column within the periodic table showcasing elements with similar chemical and physical characteristics, often influencing reactivity and bonding.
Malleable: Describes materials, especially metals, that can be easily shaped or bent without cracking or breaking, playing a crucial role in manufacturing processes.
Metalloids: Elements that exhibit a mix of metal and nonmetal properties, often used in semiconductors due to their intermediate conductivity.
Metallurgy: A specialized field focusing on the properties and behavior of metals and their alloys, encompassing extraction, processing, and application in various industries.
Metals: A category of elements known for excellent conductivity of heat and electricity, typically exhibiting ductility, malleability, and a shiny appearance.
Non-metals: Elements characterized by poor electrical and thermal conductivity, often displaying traits that contrast with metals, such as brittleness and dull appearance.
Period: A horizontal series in the periodic table that lists elements according to increasing atomic number, leading to a gradual change in properties.
Semiconductor: A material that can partially conduct electricity, providing a suitable medium for electronic applications by controlling electrical current under specific conditions.
