Study Notes
Kinetic Particle Theory
- Describes Brownian Motion, where all particles are constantly and randomly moving.
- All matter is composed of tiny randomly moving particles.
- Particle movement is determined by temperature, which is a measurement of kinetic energy related to heat.
- Higher heat means higher kinetic energy and faster average molecular speed.
- Lower heat means lower kinetic energy and slower average molecular speed.
- Energy is neither created nor destroyed, but changes form.
- Energy is the capacity to do work.
States of Matter
- Solids: Compact, fixed arrangement of atoms with strong attraction forces, low kinetic energy, incompressible and has a definite volume and shape.
- Liquids: Moderately loose arrangement of atoms, moderate attraction forces, low kinetic energy, flows/slides and has a constant volume with an indefinite shape.
- Gases: Widely spaced arrangement of atoms with a weak attraction force, high kinetic energy, compressible and has an indefinite shape and volume.
Phase Changes
- Evaporation (liquid to gas): High heat energy and temperature needed to change state.
- Condensation (gas to liquid): Low heat and temperature for a phase change to occur
- Melting (solid to liquid): Temperature increase at or above 0°C for melting.
- Freezing (liquid to solid): Temperature decreases below 0°C to freeze.
- Sublimation (solid to gas): Bypasses the liquid phase, high heat needed.
- Deposition (gas to solid): Bypasses the liquid phase, low heat needed.
Diffusion
- Movement of molecules from higher to lower concentration along a concentration gradient.
- It is a passive transport process, doesn't require energy.
Atomic Structure and Periodic Table
- Atoms are the basic building blocks of elements.
- Molecules are formed from one or more atoms bonded together.
- Atomic structure includes protons, neutrons, and electrons.
- Protons have a positive charge.
- Neutrons have no charge.
- Electrons have a negative charge.
- Atomic number is the number of protons.
- Atomic mass is the sum of protons and neutrons.
- Isotopes are different forms of the same element with varying numbers of neutrons.
Ions
- Ions are atoms or molecules with a net electric charge due to gaining or losing electrons.
- Cations are positively charged ions.
- Anions are negatively charged ions.
Bonds
- Ionic bonds: Transfer of electrons between atoms, creating oppositely charged ions that attract each other.
- Covalent bonds: Sharing of electrons between atoms to achieve stability.
- Octet rule: Atoms tend to gain, lose, or share electrons to achieve a full outer electron shell (eight valence electrons).
Periodic Table
- Elements are organized by increasing atomic number.
- Elements in the same column (group) share similar chemical properties due to similar valence electron configurations.
- Elements in the same row (period) have increasing numbers of electron shells.
