Storyboard Text

  • I sure am Car Bon. I'm a little anxious though. 
  • Hey, Oxy Gen are you ready to attend the business meeting with Mr. So Dium
  • Don't worry, relax. He's a soft person.
  • Sorry to be a bother. I was hoping to join your talks about chemistry. Could you teach me a few things about it.
  • Good afternoon gentlemen, I hope you don't mind that I brought my friend , Sil Ver.
  • Sure! Let's give you examples. One bond is a covalent bond between nonmetals. 
  • They share to fill their outer shell to act like a noble gas. It's called the Octet Rule because the outer shells should have 8 e-.
  • It would be like if I bonded with Carbon here. Two of myself would have a double bond with Carbon to create CO2.
  • Atoms bond by the outermost shell of electrons.  The atoms both give one electron to pair and create one bond.
  • Also, a nonpolar covalent bond shares electrons evenly, while a polar covalent bond gives one atom more electrons.
  • There are linear molecules that has central atoms with no excess pair and is a LINE. Bent molecules have one excess pair and the two other bonds are further down.
  • Polar covalent bonds are a result of electronegativity. This principle makes the attractive atom gains electrons and gives it a negative charge. 
  • Also, with bonds, the central atom might have excess electron pairs. This will affect the shape of the compound. It will push the bonds away from each other since like forces repel. 
  • Lastly, trigonal planar molecules has once central atom with 3 bonds that are equally spread.
  • An ionic bond would be like Mr. So Dium here gave up an electron to his wife Mrs. Chlo Rine. Now, they have one of the strongest bonds.
  • Only difference is that ionic bonds are between nonmetals and metals. 
  • Atoms lose and gain the electrons to become isoelectronic to be like noble gases for stability. 
  • Ionic bonds form when a cation and anion attract because they have opposite charges. One atom gives up an e- and the other receives it. This change creates the ions. 
  • Lastly, metallic bonds form when free floating electrons attract for the cations. 
  • They form in geometrical patterns. The patterns eventually form a lattice shape as the individual atoms alternate. 
  • It would be like if you had two of you, Sil Ver. You would be able to bend since your structure isn't rigid. The cations are able to move freely through the electrons.
