Study Notes
Chemistry Fundamentals
-
Chemistry: The study of matter's composition, structure, properties, and transformations.
-
Matter: Anything with mass and occupies space.
-
Mass: A measure of the amount of matter.
-
Compound: A substance formed by chemically bonded atoms of two or more elements.
-
Extensive Properties: Dependent on the amount of matter (e.g., volume, mass, energy).
-
Intensive Properties: Independent of the amount of matter (e.g., melting point, boiling point, density).
-
Physical Property: A characteristic observed or measured without changing the substance's identity.
-
Physical Change: A change in a substance without altering its fundamental identity.
-
Change of State: A physical change from one state (solid, liquid, gas) to another.
-
Solid: Definite volume and shape.
-
Liquid: Definite volume, indefinite shape.
-
Gas: Neither definite volume nor shape.
-
Chemical Property: A substance's ability to undergo changes that transform it into different substances.
-
Chemical Change (Reaction): One or more substances converted into different substances.
-
Reactants: Substances undergoing the reaction.
-
Products: Substances formed by the reaction.
-
Mixture: A blend of two or more substances, each retaining its identity and properties.
-
Pure Substance: A fixed composition with consistent properties and composition.
-
Organic Chemistry: The study of carbon-containing compounds.
-
Inorganic Chemistry: The study of compounds not classified as organic, primarily non-carbon compounds.
-
Physical Chemistry: The study of matter's properties, changes, and energy relationships.
-
Volume: The amount of space an object occupies.
-
Atoms and Molecules: The fundamental building blocks of matter.
-
Atom: The smallest unit of an element that retains its properties.
-
Element: A pure substance composed of only one type of atom.
-
Metals: Good conductors of heat and electricity, often malleable and ductile.
-
Malleability: Ability to be hammered into sheets.
-
Ductility: Ability to be drawn into wires.
-
Tensile Strength: Resistance to breaking when pulled.
-
Nonmetals: Poor conductors of heat and electricity (many are gases at room temperature).
-
Metalloids: Substances with properties between metals and nonmetals.
-
Homogeneous Mixtures: Uniform throughout.
-
Heterogeneous Mixtures: Not uniform throughout.
-
Law of Conservation of Energy: Energy cannot be created or destroyed.
-
Periodic Table: An organized table of elements.
-
Groups (Families): Vertical columns on the periodic table; elements in a group share similar chemical properties.
-
Periods: Horizontal rows on the periodic table.
-
Noble Gases: Nonmetals, generally unreactive gases; found in Group 18.
-
Symbol List: (Provides a list of elements and their symbols; H - hydrogen, He - helium, Li - lithium, and so forth, up to Ca - calcium).
