Examples of compounds include any substance with more than one element and a fixed ratio between them. For example, the ratio between hydrogen and oxygen atoms in a water molecule (H2O) is always 2:1. Whether you have a milliliter or 50 liters of water, every particle has the same 2:1 ratio between hydrogen and oxygen atoms. This ratio is important...
All compounds are examples of molecules, but not all molecules are compounds. According to the International Union of Pure and Applied Chemistry (IUPAC), a molecule is defined as an electrically neutral substance consisting of more than one atom. This includes compounds, plus it includes diatomic and triatomic elements, such as oxygen (O2), chlorin...
Compounds are classified according to the type of chemical bonds formed between the atoms. These bonds may be ionic, covalent, metallic, or a mixture of ionic and covalent bonds. 1. Covalent or molecular compounds are held together by covalent bonds. 2. Ionic compounds are held together by ionic bonds. 3. Complexes are held together by coordinate c...
Compound names and formulas are written listing the atom or group of atoms acting as a cation first, followed the atom or group of atoms acting as an anion second. Because atoms of elements have different oxidation states, an element may be in either the beginning or end of the formula, depending on other elements. For example, carbon (C) is a cati...

Phase: A particular state of matter [e.g. gas, liquid, solid]. Phase change: The change which occurs when a substance changes from one state to another, or undergoes a change in structure in the solid state. The common names for phase changes are: → l condensation. → s freezing.
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together. Water: two hydrogen atoms bonded to an oxygen atom. The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds.
