Presentation Transcript

  1. Take out your interactive notebook and set up an In, Out Through on your next two open pages.

  2. In Activity Why do atoms have a neutral (no) charge?

  3. IONIC CHEMICAL BONDING Atoms connect with other atoms to form chemical bonds.

  4. Types of Chemical Bonds There are four types of chemical bonds: • Ionic Bonds • Covalent Bonds • Metallic Bonds • Hydrogen Bonds

  5. Ionic Bonding • Do Atoms have an electrical charge? • The number of electrons (-) will always equal the number of protons (+) in any atom giving the atom no charge or neutrality

  6. Li F Ionic Bondingoccurs when electron(s) are transferred from one atom to another. (Metals and Nonmetals)

  7. Li+ F- Cation Anion Ionic Bonding • When electrons are lost or gained the atom becomes an ion (an atom with a charge). • Negatively charged ions are attracted to positively charged ions like the opposite poles of a magnet.

  8. Ionic Bonding with Sodium (Na) and Chlorine (Cl) results in NaCl or table salt

  9. Ionic Bonding • Here is what happens during the reaction between Sodium (Na) and Chlorine (Cl). • When Sodium loses an electron it has an overall positive charge. This is called a Cation. • When Chlorine gains an electron it has an overall negative charge and is called an Anion

  10. Here is another example of Ionic Bonding between Potassium and Fluorine.

  11. K F In an IONIC bond, electrons are lost or gained, resulting in the formation of IONS in ionic compounds.

  18. _ + K F

  19. _ + K F The compound potassium fluoride consists of potassium (K+) ions and fluoride (F-) ions

  20. _ + K F The ionic bond is the attraction between the positive K+ ion and the negative F- ion

  21. Out Activity Ionic Bonding • Draw the Electron Dot Diagram for Potassium and Iodine. • Show how these two will bond in an Ionic Bond. • Be sure to use arrows and charge symbols.

  22. Ionic Bonding Notes Complete. Stop at this slide.

  23. Covalent Bonds

  24. Continue using the Cornell notes you started with Ionic Bonding. Make a new title called “Covalent Bonding” in the through section. So what are covalent bonds?

  25. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule).

  26. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule). But rather than losing or gaining electrons, atoms now share an electron pair.

  27. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule). But rather than losing or gaining electrons, atoms now share an electron pair. The shared electron pair is called a bonding pair

  28. Chlorine forms a covalent bond with itself Cl2

  29. How will two chlorine atoms react? Cl Cl

  30. Cl Cl Each chlorine atom wants to gain one electron to achieve an octet

  31. Cl Cl Neither atom will give up an electron – chlorine is highly electronegative. What’s the solution –what can they do to achieve an octet?

  34. Cl Cl

  35. Cl Cl

  36. Cl Cl octet

  37. Cl Cl octet circle the electrons for each atom that completes their octets

  38. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle circle the electrons for each atom that completes their octets

  39. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle circle the electrons for each atom that completes their octets

  40. Cl Cl This is the bonding pair circle the electrons for each atom that completes their octets

  41. Cl Cl It is a single bonding pair circle the electrons for each atom that completes their octets

  42. Cl Cl It is called aSINGLE BOND circle the electrons for each atom that completes their octets

  43. Cl Cl Single bonds are abbreviated with a dash circle the electrons for each atom that completes their octets

  44. Cl Cl This is the chlorine molecule, Cl2 circle the electrons for each atom that completes their octets

  45. O2 Oxygen is also one of the diatomic molecules

  46. O O How will two oxygen atoms bond?

  47. O O Each atom has two unpaired electrons
