Key Info
  • How mass and atomic numbers explain atomic structure (pt 1/2)
  • Duration: 01:54
  • Two presenters use animations to show that the atomic number is the number of protons in an atom. They show that the mass number minus the atomic number is the number of neutrons. They complete the atomic structure by explaining that atoms have the same number of protons and electrons. A follow up to this example is given in the second part of the clip.
  • Subject:

    Chem: Periodic Table and Atomic Structure

  • Keywords: atom, atomic, electron, proton, neutron, mass, structure
Ideas for use in class
  • This clip could be used to show how mass and atomic numbers can explain the numbers of protons, neutrons and electrons in atoms. After watching it, students could use different examples from the Periodic Table to demonstrate what they have learned. You could then show part 2 of this clip - clip no 10661.
