Introduction to chemistryA big picture view of chemistry and why it is fascinating. How chemistry relates to math and other sciences.

Measurement, Significant Figures & Dimensional Analysis

Measurements in Chemistry
- Accuracy & Precision
- Determination and Analysis of Error
Using Significant Figures to Communicate Precision
Converting Units using Dimensional Analysis

Intro to significant figuresSignificant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.

Classification of Matter & Properties

Matter is a substance or mixture of substances
Matter can be classified as an element, compound or mixture
The composition of a pure substance is determined by the ratio of atoms present

Atoms & Ions

An atom is the smallest unit an element
Atoms can be identified by its electron distribution and energy

Introduction to chemistryA big picture view of chemistry and why it is fascinating. How chemistry relates to math and other sciences.

Isotopes

Isotopes of an element have the same number of protons and different number of neutrons.
The mass spectrum of an element determines the identity of isotopes for an element and the relative abundances of each isotope.

Atomic weight and atomic massAtomic mass is the total mass of protons and neutrons in an individual atom or isotope. Atomic weight is the average mass of all of the naturally-occurring isotopes of an element. Both atomic mass and atomic weight are represented using a unit called the atomic mass unit (amu), which was defined using carbon's most common isotope, carbon-12.

Writing Chemical Formulas & Naming Compounds

Chemical formulas identify substances by their unique combination of atoms
The formula for a substance is the fixed ratio of atoms present
Substances use systematic (IUPAC or stock system) of naming.

Naming ions and ionic compoundsIonic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K+ and Cl- ions, is named potassium chloride.

Chemical Reactions & Balanced Equations

Chemical reactions result in chemical changes of substances
Chemical reactions follow the Law of Conservation of Mass & Energy
Balanced chemical equations show conservation of atoms and therefore conservation of mass.
Chemical reactions may be synthesis, decomposition, single replacement, double replacement or combustion.

Chemical reactions introductionReactants and products in reversible and irreversible chemical reactions.
