Study Notes

Atomic Structure and Bonding

Atoms are the fundamental building blocks of matter, composed of a nucleus containing protons and neutrons, surrounded by orbiting electrons.
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
The atomic number represents the number of protons in an atom, defining the element.
The mass number is the sum of protons and neutrons.
Isotopes are atoms of the same element with varying numbers of neutrons.
Electrons occupy specific energy levels (shells) and sub-levels (orbitals).
Valence electrons are the electrons in the outermost shell and are crucial for chemical bonding.
Ionic bonding involves the transfer of electrons between atoms, forming positively charged cations and negatively charged anions.
Covalent bonding involves the sharing of electrons between atoms, forming molecules.
Metallic bonding involves the delocalization of valence electrons, creating a "sea" of electrons that holds metal atoms together.

Chemical Reactions

Chemical reactions involve the rearrangement of atoms to form new substances.
Reactants are the substances that undergo change, and products are the substances formed.
Balanced chemical equations represent the conservation of mass in a reaction, with equal numbers of atoms of each element on both sides.
Chemical reactions can be classified based on various factors, such as the type of reaction (synthesis, decomposition, single displacement, double displacement).
Exothermic reactions release heat to the surroundings, while endothermic reactions absorb heat from the surroundings.
Reaction rates depend on factors such as temperature, concentration, surface area, and presence of catalysts.
Catalysts speed up reactions without being consumed.
Le Chatelier's principle describes how a change in conditions (e.g., temperature, pressure, concentration) affects the equilibrium of a reversible reaction.

States of Matter

Matter exists in four states: solid, liquid, gas, and plasma.
Solids have a fixed shape and volume, with strong intermolecular forces holding particles in place.
Liquids have a definite volume but take the shape of their container. Intermolecular forces are weaker than in solids.
Gases have neither a definite shape nor volume, with particles widely dispersed and weak intermolecular forces.
Plasma is a highly energized state of matter, with electrons stripped from atoms.

Solutions

Solutions are homogeneous mixtures of two or more substances, where one substance (solute) is dissolved in another (solvent).
Solubility describes the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.
Concentration expresses the amount of solute in a given amount of solution. Various units are used (e.g., molarity, molality, percent by mass).
Colligative properties of solutions depend on the number of solute particles, not their chemical identity (e.g., vapor pressure lowering, boiling point elevation, freezing point depression, osmotic pressure).

Acids and Bases

Acids are substances that donate protons (H+ ions) in an aqueous solution.
Bases are substances that accept protons (H+ ions) in an aqueous solution or donate hydroxide ions (OH−).
The pH scale quantifies the acidity or basicity of a solution; a lower pH indicates higher acidity, a higher pH indicates higher basicity.
Strong acids and bases completely dissociate in water, while weak acids and bases only partially dissociate.
Neutralization reactions involve the reaction of an acid and a base to form a salt and water.

Periodic Table

The periodic table organizes elements by atomic number and recurring chemical properties.
Elements in the same group (vertical column) share similar chemical properties due to similar valence electron configurations.
Elements in the same period (horizontal row) show gradual changes in properties across the period.
Metals generally are good conductors of heat and electricity and tend to lose electrons.
Nonmetals generally are poor conductors of heat and electricity and tend to gain electrons.
Metalloids have properties intermediate between metals and nonmetals.

Nomenclature

Chemical nomenclature provides a systematic way to name chemical compounds.
Rules specify how names reflect the composition and structure of the compounds.
Different naming conventions apply to inorganic and organic compounds.
