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 ... 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

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

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

The characteristic of a convertible bond The convertible bond is one kind of equity-linked bonds. The term of the bond entitles bondholder to convert bonds into shares of the company or another company in the same group‚ at an agreed-upon conversion price‚ among a fixed period. The reason why it is made in this form is that the issuer can benefit from four aspects as follow‚ (1) better terms. A convertible bond have a lower interest rate‚ less restrictive covenants or the subordination of bondholders’

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.

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
