  1. Bond, Chemical Bond By Chloe Nagle Bond, James Bond

  2. Types of Bonding • Covalent • Ionic • Metallic

  3. Ionic Bonding • Usually formed by metals and non-metals bonding. • Oppositely charged atoms are attracted like magnets. • One atom gives up and electron and the other atom takes that electron. Click here for a video of Ionic Bonding

  4. Ionic Bonding Ionic bonds are held together because they have opposite magnetic charges. They are very soluble in water and they are good conductors of electricity. When the elements’ electronegativities are further apart (I.e. Fluorine and Francium), the bond is stronger because the positive charge is so weak and the negative charge is very strong.

  5. Ionic Bonding Examples of Ionic Bonded Compounds • Salt • Magnesium Oxide • Calcium Chloride • Potassium Oxide Difference of electronegativitys is >1.7. Electron stays with the stronger element. Click here for a video of Ionic Bonding

  6. Ionic Bonding This type of bonding is unique because this is the only bond where the electron is completely taken from one element and given to the other instead of sharing. Click here for a video of Ionic Bonding

  7. Covalent Bonding • This is when atoms share two or more electrons. • Depends on the atoms’ electronegativity. • Atoms do not have to be the same, though are sometimes. Click here for a picture of Covalent Bonding.

  8. Covalent Bonding Covalent bonds are held together by the electrons they share. Between 0 and 0.3 is just a covalent bond. Between 0.4 and 1.7 is called a polar covalent bond. Covalent bonds are very stable. Click here for a picture of Covalent Bonding.

  9. Covalent Bonding Examples of Covalent Bonds • Chlorine • Hydrogen • Hydrogen Chloride • Carbon Dioxide • Carbon Tetrafluoride Click here for a picture of Covalent Bonding.

  10. Covalent Bonding This bond is unique because the elements share the electrons instead of just taking them. They generally deal with carbon-based compounds, organic compounds. Click here for a picture of Covalent Bonding.

  11. Metallic Bonding • All electrons are shared between the elements. • Electrons revolve around all atoms because of the various spots that they can be.

  12. Metallic Bonding Metallic bonds are held together by the electrons that are floating around them. It doesn’t really have anything to do with electronegativity. Because the nucleus has a positive in all elements, the electrons are attracted to both elements.

  13. Metallic Bonding Examples of Metallic Bonds: • Zinc • Potassium

  14. Metallic Bonding Metallic bonds are unique because they are the only bonds that share ALL of their electrons instead of just one or two. They are also unique because the electrons float around instead of staying in fixed orbitals.

  15. Comparing and Contrasting the Bondings All have to do with electrons. They’re all chemical bonds. Metallic bonds don’t really have to do with electonegativity. Covalent bonds share two electrons. Metallic bonds share all of their electrons. Ionic bonds give away electrons or take electrons.

  16. Class References In class, we talked about electronegativity. That has a lot to do with bonding because when you bond two elements together, the type of bond depends on the difference of their electronegativities.
