Study Notes
Chemistry 101 Cumulative Exam Review
- Chemistry: The study of the composition, structure, properties, and reactions of matter.
- Chemical: A substance with a constant composition and properties.
- Element: A pure substance comprised of only one type of atom.
- Compound: A substance formed from the combination of two or more elements.
- Pure substance: Composed of only one element or one compound.
- Mixture: Composed of two or more different substances not chemically joined.
- Metal: Shiny, metallic luster, reflective surface.
- Nonmetal: Generally dull, non-reflective.
- Metalloid: Has metallic or nonmetallic appearance depending on the element.
Atomic Structure and Properties
- Atomic number: The number of protons in an atom's nucleus; determines an element's chemical properties.
- Mass number: The total number of protons and neutrons in an atom.
- Isotope: Atoms of the same element with different numbers of neutrons.
- Average atomic mass: The weighted average mass of all naturally occurring isotopes of an element.
- Valence electrons: Electrons in the outermost electron shell of an atom, involved in chemical bonding.
- Half-life: The time taken for half of a radioactive isotope to decay.
Chemical Bonding and Reactions
- Fission: The splitting of a nucleus into two or more parts.
- Chain reaction: A reaction where the products themselves promote the reaction.
- Fusion: The joining of two nuclei to form a larger one.
- Octet rule: Atoms tend to gain, lose, or share electrons to achieve a full outermost electron shell (eight electrons).
- Ionic bond: Formed by the electrostatic attraction between oppositely charged ions.
- Covalent bond: Formed by the sharing of electrons between atoms.
Solutions and Mixtures
- Solution: A homogeneous mixture of two or more substances, where one substance (solute) dissolves in another (solvent).
- Solute: The substance that is dissolved.
- Solvent: The substance that dissolves the solute.
- Electrolyte: A substance that conducts electricity when dissolved in water.
- Saturated/Unsaturated/Supersaturated Solutions: Solutions with varying concentrations of solutes.
- Arrhenius Acid: Increases H⁺ ion concentration in solution
- Arrhenius Base: Increases OH⁻ ion concentration in solution
- Bronsted-Lowry Acid: A proton (H⁺) donor
- Bronsted-Lowry Base: A proton (H⁺) acceptor
- Amphoteric Substance: Can act as either an acid or a base.
Other Concepts
- Molar mass: The mass of one mole of a substance.
- Combustion reaction: A reaction that produces heat and light.
- Decomposition reaction: A reaction where a substance breaks down into two or more substances.
- Synthesis reaction: Two or more substances combine to form one.
- Single replacement reaction: An element in a compound is replaced by another element.
- Double replacement reaction: The ions of two compounds swap places to form two new compounds
- Endothermic reaction: Absorbs heat
- Exothermic Reaction: Releases heat
- Gas Laws: Various laws governing gas behavior (Charles' Law, Avogadro's Law, Gay-Lussac's Law, Dalton's Law).
Other Chemical Concepts (Additional from pages)
- Organic Compounds: Compounds containing carbon; examples include carbohydrates, proteins, lipids, nucleic acids.
- Enantiomers: Pairs of molecules with a mirror-image relationship.
- Steroids: Four fused hydrocarbon rings.
- Carbohydrates: Sugars and starches.
- Amino Acids: Building blocks of proteins.
- Proteins: Complex molecules made of amino acids, involved in various cellular functions.
- Nucleic acids: DNA & RNA; store and transmit genetic information

- Nomenclature: Naming chemical compounds.
- Ion formation, Nomenclature: Methods for naming ions and ionic compounds.
- Covalent Nomenclature: Naming covalent compounds.
- Metric Conversions: Conversion of units (grams to kilograms, etc.).
- Stoichiometry calculation: Using balanced chemical equations to determine quantitative relationships in chemical reactions.
Periodic Table Trends (Partial from pages)
- Atomic Size: Across a period (left-to-right) generally decreases, down a group (top-to-bottom) increases.
- Electronegativity: Across a period increases, down a group decreases.
- Ionization Energy: Across a period increases, down a group decreases.
