Storyboard Text

  • Hey! Heard we might be learning about intermolecular forces today!
  • I know there's 3 different types of those: covalent, metallic, and ionic. There's also two types of covalent bonds: polar and non-polar
  • No way! I know way to much about that already!
  • Uhh...a church now?
  • And before you ask: yes, atoms typically have big electromagnetic difference when they're in an ionic bond
  • Of course! Now, ionic bonds happen between metallic and non-metallic atoms. A transfer of electrons also occurs
  • The electrons then go and surround the positive ions
  • Metallic bonds happen between metal atoms. The atoms give up their valence electrons and change into cations.
  • So I kinda know some about polar and non-polar bonds. They share electrons when they're in covalent bonds.
  • Yup, that's true. They typically happen between non-metals, but can sometimes happen between a mental and non-metal. Oh, and I'm invisible now
  • In a PCB, valence electrons aren't shared equally between the atoms. They have a partial, but still relatively high, charge. The structure is also asymmetric.
  • The valence electrons are split equally in a NPCB. Diatomic molecules usually don't have a difference in electronegativity.
