PPT-Covalent Bonding: Orbitals

DE Chemistry Dr Walker Hybridization and the Localized Electron Model Hybridization The mixing of two or more atomic orbitals of similar energies on the same atom to produce new orbitals of equal . and . Electronegativity. Presented by . Leticia Bonita Prince. Newcastle University 4. th. Year . MChem. Student. Aims of Today. Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. 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. Chapter 9 ~ most compounds, including those in living organisms, are covalently bonded. What You’ll Learn. I will analyze the nature of a covalent bond. I will name covalently bonded groups of atoms. Chapter 9. Molecular Geometry and Bonding Theories. Molecular Geometry .
