A naturally occurring element that typically has a shiny surface, high thermal and electrical conductivity, and is malleable and ductile, enabling it to be shaped into various forms for practical use, such as tools or structural components.
A classification of solid substances that includes materials like gold, silver, copper, and aluminum, characterized by their ability to conduct heat and electricity well, as well as their strength and ability to be easily formed or drawn into wires and sheets.
A term that refers collectively to various metallic elements and their alloys found in nature, known for possessing distinctive luster and being capable of significant structural applications due to their physical properties.
Refers to a group of substances within the periodic table that exhibit particular properties like electropositivity and a tendency to lose electrons, which leads to the formation of other materials such as alloys through combining different metals.
Example:
鉄は最も有用な金属です。
Having a composition that is primarily metal, often characterized by durability and a shiny appearance.
Composed of various types of metals, typically used to denote objects or materials that require strength or conductivity.
Pertaining to items or structures that exhibit properties of metal, such as hardness and resistance to corrosion.
Example:
それは木製ですか、それとも金属製ですか。
A sharp, high-pitched sound produced when metal is struck or rubbed against a hard surface, often reminiscent of the ringing of metal objects.
The distinctive, resonant noise that occurs during interactions with metal materials, frequently associated with machinery or tools.
An auditory sensation characterized by a bright, clangorous quality, typically associated with metallic instruments or structures in motion.
A rare and valuable type of metal that resists oxidation in the atmosphere and is not prone to chemical changes, often associated with luxury and high economic worth, typically including gold, silver, and platinum.
Metals that are considered precious due to their limited availability and desirable qualities, such as resistance to corrosion and the ability to maintain a beautiful luster, commonly used in jewelry, electronics, and as investment assets.
A category of metals distinguished by their scarcity, durability, and aesthetic appeal, often used as a standard for monetary value and investment, including elements like gold and platinum.
A device designed to detect the presence of metal objects, often used in security screenings at locations such as airports to prevent the bringing of weapons or prohibited items.
An electronic instrument that identifies metallic substances, commonly used in various contexts including treasure hunting, construction, and safety checks.
