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

Chapter 10: Bond Return and Valuation Q. 6. Find out the yield to maturity on a 8 per cent 5 year bond selling at Rs 105? Solution: Yield to Maturity = [pic] = [pic] = [pic] × 100 = [pic] × 100 YTM = 6.82. Q. 7. (a) Determine the present value of the bond with a face value of Rs 1‚000‚ coupon rate of Rs 90‚ a maturity period of 10 years for the expected yield to maturity of 10 per cent.

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

HOMEWORK ASSIGNMENT 1. Callaghan Motors’ bonds have 10 years remaining to maturity. Interest is paid annually‚ they have a $1‚000 par value‚ the coupon interest rate is 8%‚ and the yield to maturity is 9%. What is the bond’s current market price? PV factor of sum = (1+i)^-n = (1+9%)^-10 =1.09^-10 = 0.4224 PV factor of annuity = 1 - (1+i)^-n / i = 1 - (1+9%)^-10 / 9% = 1 - 0.4224 / 9% = 0.5775 / 9% = 6.417 = PV factor of Sum * Par Value + PV factor of annuity * coupon payment = 0.4224 * 1‚000
