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

A Broken Bond From the moment that the mother feels her child kicking‚ there is a very strong bond developed. In one’s life‚ a strong maternal bond is crucial. In Laura Esquivel’s novel Like Water for Chocolate‚ it seemed liked Mama Elena was unaware of the importance of this relationship. “Unquestionably‚ when it came to dividing‚ dismantling‚ dismembering‚ desolating‚ detaching‚ dispossessing‚ destroying‚ or dominating‚ Mama Elena was a pro.” Mama Elena was destined to ruin Tita’s life.

When a metallic substance shares electrons with a non-metal substance it forms covalent bonds‚ which make molecules. The metal becomes positively charged atoms‚ which means that the number of electrons is never less than the number of protons. Non-metals become negatively charged atoms‚ and now the number of electrons is more than the number of protons. When atoms share electrons of nonmetals then a covalent bond is formed inside the molecule. Monatomic elements are elements that only contain one type

Information compiled by ___________________________________________________________ Stocks have historically had much higher returns than bonds. Can these excess returns be justified by the higher risk attached to stocks‚ or are there alternative explanations? The following is an abbreviated history of studies and models that articulate the logic of stock returns; included are both support for and alternatives to the equity risk premium.

Question 5 energy prices permanently increased The rise in energy prices reduces the productivity of capital per worker. This causes sf(k) to shift down from sf1(k) to sf2(k). The result is a decline in steady-state k. Steady-state consumption per worker falls for two reasons: (1) Each unit of capital has a lower productivity‚ and (2) steady-state k is reduced. population growth rate permanently increased due to increased immigration Immigration raises n from n1 to n2.

keeping many businesses afloat. The bond market is another environment where debts are issued and taken up by investors. As a capital market it is concerned with loans with long-term maturities (5-30 years) and companies use them to invest in new facilities etc. thus increasing growth opportunities.

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic
