Storyboard Text

  • waaaaah! waaaah! mommy mommy! today all the kids at school made fun of me becuase i am unstable and my valence shell is incomplete. what do i do!
  • Oh dear, that is a problem, dont you worry, tomorrow we will figure something out
  • But i don't even know what that means, valence shell..what is it mum?
  • Ahh, well your valence shell is your outer most shell in an atom, ours, like most noble gasses, has too little electrons to be stable, less than 8, so we must find a pair to share an electron with, so both of you can be stable.
  • good idea mom
  • why don't you try forming a bond with him?
  • I dont have a covalent bond.
  • Hey! i heard you're an unstable chlorine atom just like me! you wanna form a bond?
  • OK!
  • Hey! of course! finally. we can share 1 electron since we ony have 7 each in our valence shell.
  • Its ok i'll take it and become a negatively charged anion.we'll be ionically bonded.
  • But who's that, why is he taking an electron?
  • Ok then.
  • Oh no i just lost an electron, im a positively charged cation.
  • YAY we're both bonded and finally stable.
  • Well, he is forming an ionic bond, where the metal, sodium looses an electron and gives it to the non metal chlorine.
  • Right! so they give and take to stabalise and never share.
