Transcript of Chemical Bonding Project

by Josh Coady Chemical Bonding Project characteristics Ionic Bonding Ionic Bonding Helpful video Characteristics Covalent Bond What are they? Valence Electrons and Bonding Covalent Bonding Helpful Video Electronegativity Periodic trends and bonding Sources Formed between nonmetals and metals One atom steals the electron/electrons from the other. usually the non metal takes from the metal Forms between non-metal and non-metal The attraction (which ends up bonding) is between the protons and electrons Unlike an ionic Bond where typically the non-metal steals the electron from the metal, covalent Bonds share the electrons evenly between the atoms. Red electrons are the original carbon atoms Blue electrons are the hydrogen's electrons the goal is for the compound to reach a significant 8. They share each other's electrons in order to reach that goal. A Valence Electron is the name given to the electrons in the outer most energy level of atoms SO? So these are the electrons important in bonding Ionic bonds In an ionic bond the valence electrons are stolen from the metal by the non-metal in order to make a significant 8. Covalent Bonds In a covalent bond the valence electrons are shared in order to make a significant 8. This Picture illustrates the valence electrons of CH4 being bonded covalently. this picture illustrates how the electron of Na will be stolen by Cl thus causing Cl to be negatively charged and Na positively charged causing the two atoms to stick together. Electronegativity is the ability of an atom to pull of another atom The bond between two atoms depend on the difference between the electronegativities of those atoms Ionic bonds are formed when this difference is high Covalent bonds are formed when these differences are low http://www.askmehelpdesk.com/chemistry/how-does-periodic-trends-affect-boding-610471.html en.wikipedia.org/wiki/Ionic_bond en.wikipedia.org/wiki/Covalent_bond
