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

of Bonds Fixed rate bonds have a coupon that remains constant throughout the life of the bond. A variation are stepped-coupon bonds‚ whose coupon increases during the life of the bond. Zero-coupon bonds (zeros) pay no regular interest. They are issued at a substantial discount to par value‚ so that the interest is effectively rolled up to maturity (and usually taxed as such). The bondholder receives the full principal amount on the redemption date. High-yield bonds (junk bonds) are bonds that

1. Explain the difference between a peptide bond and a sulfide bond. Draw an example of each. (Insert a picture of your drawing of the molecule or a scan of your drawing of the molecule) A peptide bond is a covalent bond. This bond is between two amino acid molecules. The formation of a peptide bond occurs when a carboxyl group present on one molecule reacts with an amino group that is present on the molecule. This reaction releases H2O. In organic chemistry‚ I learned that a sulfide bond has to

separated atoms. The bound state implies 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

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds‚ in
