化合物可以分为无机化合物(inorganic compound)与有机化合物(organic compound)两种,也可以按照化学键类型划分为共价化合物(covalent compound),离子化合物(ionic compound)与络合物(coordinate complex)等。 2.2 共价化合物的命名法 - Covalent Compound Nomenclature 化合物的化学式是根据元素的化合价[1]决定的,一般正价...
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
Atoms and the Periodic Table Dr. Childs Science Laboratory Spring, 2004 Cote d'Ivoire Overview This lesson has 4 parts: 1. Structure of the atom 2. Periodic table 3. Valence electrons / chemical reactivity 4. Ionic and covalent bonds 1. Structure of the Atom Nature of the Atom The period...

Elements can form two main types of bonds, ionic and covalent. Covalent bonds are a sharing of electrons. Lewis dot structures are a simple way of showing those covalent bonds. Read Octet Rule & Lewis Structure | Definition & the Periodic Table Lesson ...
atom's outermost shell; these are called the valence electrons, and they are the electrons that can chemically bond with valence electrons of other elements. The valence electrons can be either shared with another element, in covalent bonding, or exchanged via ionic bonding, according toPurdue ...
clear as the order of the oxygen-oxygen bond is double. In this case, and indeed for most of the periodic table, it is necessary to infer the covalent radius from molecules containing O-O single bonds or from molecules containing a C-X bond in which the covalent radius of X is known....
