by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point‚ solubility‚ and conductivity‚ can be used to predict the type of bond that binds

INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical

Chemical bond From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such

a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom. Hydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as

Corporate Bonds‚ Common stock‚ and Preferred Stock Higher return means higher risk. People use excess money to invest in a corporation. It is a good way gain more money than put money into the saving account to get a little interest. Before you invest you should analyze the characteristics of corporate bonds‚ common stock‚ and preferred stock; and also be aware of their advantages and disadvantages. The corporate bonds are issued by corporations. They are used to increase capital for issuing

Covalent Bonds Covalent bonds are formed when atoms share electrons‚ one from each atom in a single bond‚ to form electron pairs‚ usually making their outermost shells up to eight electrons by this means. This would make them more stable‚ less reactive and an electronic structure like a noble gas. They are most frequently formed between pairs of non-metallic elements. Non-metallic elements usually have from four to eight electrons in their outermost shells‚ the so-called valency electrons‚ which
