Definition: The process of covering or treating a surface with a layer of metal.

Example: The metallization of the surface improved its conductivity and durability.

Definition: Describing a substance that has properties between those of metals and nonmetals, often appearing metallic in nature.

Example: Silicon is a metalloid that is widely used in electronics.

Definition: A type of element that has properties of both metals and nonmetals, often used in semiconductors and alloys.

Example: Silicon is a common metalloid used in electronics.

Definition: Relating to or having the properties of a metalloid, which is a type of element that has characteristics of both metals and nonmetals.

Example: Silicon is considered a metalloidal element because it exhibits properties of both metals and nonmetals.

Definition: In a way that relates to the science and technology of metals, including their extraction, processing, and properties.

Example: The engineers metallurgically analyzed the samples to determine their composition.

Definition: A person who specializes in the study and processing of metals, including their properties and how to work with them.

Example: The metallurgist analyzed the metal samples to determine their composition and strength.

Definition: The field of science that focuses on the extraction, purification, and creation of metals and metal objects.

Example: Metallurgy is essential for developing new materials for construction and manufacturing.

Definition: Describing rocks that have been changed in structure or composition due to heat and pressure, or relating to a process of transformation.

Example: Metamorphic rocks, such as marble and schist, are formed from existing rocks that undergo significant changes.

Definition: The process in which rocks change their structure, texture, or composition due to high heat, pressure, or new chemicals.

Example: Metamorphism can transform limestone into marble under the right conditions.

Definition: To change or transform completely in form or appearance, often in a way that is significant or dramatic.

Example: The caterpillar will metamorphose into a butterfly after a few weeks.

Definition: To change completely in form or appearance; to transform into something different.

Example: The caterpillar will metamorphose into a butterfly after it forms a cocoon.

Definition: A significant change in form, appearance, or character, often involving transformation, such as in the life cycle of certain animals or in a metaphorical sense.

Example: The caterpillar underwent a metamorphosis to become a beautiful butterfly.
