Study Notes

Scientific Skills & Notation

Rounding off numbers to a specified number of digits is essential for precision.
Powers of 10 and exponent laws are fundamental to understanding scientific notation.
Scientific notation is used for expressing very large or small numbers in a compact form.
Practice conversions between standard form and scientific notation with or without calculators.
Familiarity with SI symbols and units is crucial for scientific communication.
Ability to convert units into SI units, using common conversion factors in mass, length, volume, temperature, and pressure.
Recognizing and converting various metric scales aids in accurate measurements.
Orders of magnitude help understand the scale of differences between quantities.
Mathematical manipulations and equations are vital for scientific analysis.
Understanding the scientific method involves variables, data collection, and hypothesis testing.
Proficient use of tables and graphs enhances data interpretation.
Direct and inverse relationships in graphs show how variables are related.

Classification of Matter & Kinetic Molecular Theory

Matter is classified into mixtures (homogeneous and heterogeneous) and pure substances (elements and compounds).
Familiarity with names and formulas of substances is necessary.
Kinetic Molecular Theory (KMT) describes all matter as composed of tiny particles (atoms and molecules) that are too small to see.
Matter exists in five phases, with each phase having different particle arrangements.
Phase changes such as melting and boiling are defined by specific temperatures.

The Atom

Atomic models have evolved through key discoveries, influenced by five major contributors.
Atoms consist of protons, neutrons, and electrons.
The atomic number of an element indicates the number of protons; neutral atoms have equal protons and electrons.
Neutron number is calculated by subtracting the atomic number from the mass number.
Isotopes are variants of elements with the same number of protons but differing neutron counts.
Nuclei can be represented in the notation [Z^A^E].
Electron configurations describe how electrons are arranged in atomic orbitals, following the Aufbau principle, Hund's rule, and Pauli's Exclusion Principle.

Periodic Table

The periodic table arranges elements in ascending atomic number, reflecting electron configurations.
Understanding the arrangement clarifies group and period numbers, valence electrons, and valency.
Periodic trends include atomic radius, ionization energy, electron affinity, and electronegativity.

Chemical Bonding & Equation Writing

Covalent bonding involves sharing electrons, forming single, double, or triple bonds; molecular formulas and electron diagrams represent these compounds.
Ionic bonding relies on electron transfer, creating cations and anions, with specific naming conventions for ionic compounds.
The structure of ionic crystals is based on ionic bonding principles and results in the formation of salts.
Metallic bonding is characterized by a 'sea of electrons' contributing to properties like conductivity.
Writing balanced chemical equations is essential, representing conservation of atoms and relative atomic masses.
Word equations must be translated into chemical equations for clarity, using symbols to indicate phases (s), (ℓ), (g), and (aq).

Waves Basics

Transverse waves consist of alternating crests and troughs, with definitions for wavelength, frequency, amplitude, and period.
Wave speed is determined by the relationship between frequency and wavelength.
Concepts of "in phase" and "out of phase" describe the alignment of waveforms in a wave system.
