Study Notes
Periodic Table
- Metals and non-metals are categorized based on their conductivity; metals conduct electricity and heat well, while non-metals do not.
- Transition metals are found in the center of the periodic table, forming colorful compounds and having variable oxidation states.
- Noble gases are in group 18 and are unreactive due to full valence electron shells.
- Trends in properties of elements are observed across rows (periods) and columns (groups).
- Periods and groups classify elements based on their properties.
IUPAC Naming and Classification
- Alkanes are saturated hydrocarbons with single bonds between carbon atoms (e.g., methane, ethane).
- Alkenes are unsaturated hydrocarbons with at least one double bond between carbon atoms (e.g., ethene).
- Alcohols are organic compounds containing a hydroxyl group (-OH) (e.g., ethanol).
- Carboxylic acids are organic acids containing a carboxyl group (-COOH) (e.g., acetic acid).
- Esters are organic compounds derived from carboxylic acids and alcohols, often with pleasant smells (e.g., ethyl acetate).
The Atmosphere
- Gas properties are defined and measured by pressure, volume, and temperature.
- Earth's atmosphere is a mix of gases (e.g., nitrogen, oxygen).
- Testing and treatment methods analyze air quality and purification techniques are used to purify air.
- Extraction, emission, and environmental impacts cover processes, pollution release, and effects on the environment.
Matter
- Matter exists in solid, liquid, and gas forms. Characteristics include density and boiling point.
- Particle/kinetic theory suggests that matter consists of moving particles.
- Diffusion is the spreading of particles from high to low concentration.
- Atoms are made up of protons, neutrons, and electrons. Electron configurations describe electron distribution within atomic orbitals.
- Valency refers to an element's combining capacity, usually involving electrons.
Bonding
- Atoms connect via ionic, covalent, and metallic bonds.
- Chemical formulas and reactions involve atomic symbols and ratios.
- Chemical kinetics studies reaction rates and influencing factors.
- Equilibrium reactions reach a balance between forward and reverse reactions.
- Energy changes in reactions can be endothermic (absorbing heat) or exothermic (releasing heat).
- Combustion reactions involve burning fuels to release energy (often releasing carbon dioxide and water).
Types of Chemical Reactions
- Acids donate protons (H+), and bases accept protons.
- Neutral solutions have a pH of 7.
- Acid/base reactions produce water and salts.
- Redox reactions involve electron transfer (oxidation and reduction).
- Reactivity series lists metals in order of reactivity, from highest to lowest. Metal extraction retrieves metals from their ore.
- Corrosion is a metal's gradual deterioration by chemical reactions, typically happening in the environment.
Electrochemical Cells
- Electrochemical cells transform chemical energy into electrical energy via redox reactions.
