Storyboard Text

  • HAHA remember when we were younger and we would breathe in a little helium to make a funny voice
  • I wonder what's helium is made of and how it makes our voices sound like that
  • Let's try it again, because it's so funny...Wait what's happening!!!
  • Oh no we are shrinking!! Wait why are we entering an atom, I think its the helium atom?
  • Helium is a chemical element with the symbol (He) and the atomic number 2
  • helium is the second most common element (after hydrogen)
  • The atomic number is 2 and the definition of an atomic number ishe number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
  • There are 2 protons , 2 electrons and 2 neutrons. The nucleus being in the middle and the only and outer most electron shell
  • Heliums atomic mass is 4.002602 and the definition of atomic mass is the mass of a single atom of a chemical element. It includes the masses of the 3 subatomic particles that make up an atom: protons, neutrons and electrons.
  • Helium is found in period 1 and group 8 or 18. A group is the columns on the periodic table going down and periods go across
  • The electron configuration of helium is 2 and the valence electron is 2
  • Well I heard helium is colourless, odourless and tasteless
  • Wow that was something!! I think the helium has finally worn off.
  • That was really weird but how amazing is it now that we know all this information about helium??!!
  • everyones gonna think we are sooo smart now
