ELEMENTS OF PERIODIC TABLE Flashcards
The lightest and most abundant chemical element, usually found in combination with other elements, forming water and organic compounds.
Hydrogen (H)
A highly reactive nonmetallic element essential for respiration by living organisms and combustion.
Oxygen (O)
A nonmetallic chemical element that forms the basis for all known life and many organic compounds.
Carbon (C)
A dense, soft, yellow, precious metal, often used in jewelry, currency, and electronics.
Gold (Au)
A colorless, odorless, inert gas, often used in lighting, advertising signs, and vacuum tubes.
Neon (Ne)
A metallic chemical element, essential in steelmaking and widely used in construction and manufacturing.
Iron (Fe)
Definition: A nonmetallic element, essential in the production of semiconductors, ceramics, and glass.
Silicon (Si)
The second lightest element. Low boiling and melting points, does not readily form chemical compounds.
Helium (He)
A highly reactive metallic element, commonly found in salt and used in various industrial processes.
Sodium (Na)
A highly reactive nonmetallic element, commonly used in disinfectants, bleach, and PVC production.
Chlorine (Cl)
A collection of elements that share common characteristics or properties and exhibit similar behavior under certain operations or transformations.
Groups
A larger collection of elements grouped together based on common attributes or characteristics, often exhibiting a hierarchical structure with subsets or subfamilies.
Families
A specific interval or duration during which an element belongs to a particular group or family, often determined by its atomic number or chemical properties.
