  • Hey Riley, why is this mall so bland? There is no color in here at all!!
  • Atomic radius is a measurement of the size of a neutral atom. Ionic radius is the measurement of the size of an ion (an atom is mostly empty space between nucleus and electrons).
  • That's because we are on the left side of the mall. The boring colors will decrease as we move right, I promise. Just like the periodic table, atomic and ionic radius decreases as you move right!
  • Ionization energy is the energy that is required to remove an electron from an atom in a gas state of matter.
  • See, there is less bland colors here on the right side of the mall. There is also more people on this side of the mall, just like how ionization energy increases as you move right.
  • Electronegativity is the ability of an element to attract an electron within a covalent bond.
  • We've made it to the most colorful part of the mall! It also looks like you really like the toys on the shelf, just like an atom's electronegativity.
  • You do realize I'm only 8 years old and don't understand most of what you are telling me, right?!?
  • Thank you for teaching me about your fascination with chemistry today, Riley!
  • You're welcome Kate! One more thing, just like how you went down the escalator, metallic character increases as you move down a family in the periodic table!
  • Metallic character is the level of reactivity in a metal.
  • Even though Kate didn't understand what Riley told her when she was young, little did she know she would grow up to be a chemist in a big city!
