Conceptually these zeroes ar e the building blocks of all securities with fixed cash flows Combining zeroes in a portfo lio creates an asset with multiple fixed cash flows We can structure portfolios of zeroes to replicate existing securities such a Elements with high electronegativities (non-metals) will not give up electrons. Bonds are not formed by a transfer of electrons, they are formed by sharing electrons.. Molecules are neutral groups of covalently bonded atoms. COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). Amanda Lyne Green Fleet Scotland 2015. “Hydrogen Miles TODAY” . Direct replacement of hydrocarbon fuel with hydrogen . Uses combustion technology (reduces technical risk and cost). No need . to change duty cycle . Why Water is Special. Why do we study water properties in biology class?. About 2/3 of the mass of a cell is water!. Most life-sustaining reactions occur in water solutions. Polarity. Polarity describes the distribution of electrons in a molecule. Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. Traditionally known as a “safe investment”. Typically less volatile than stocks. Offer regular interest payments. Have first priority in any liquidation. The Safer Alternative to Bonds. . Jim Royal (September, 2011). Chemistry 11. Ms. McGrath. Functional Groups. A functional group is . a reactive group of bonded atoms that appears in all the members of a chemical . family.. .
