The Smallest One
a: Hydrogen ~
b: a ping pong ball
What: "The answer turns out to be quite simple. Hydrogen is the smallest atom in the world, so the hydrogen is like a ping pong ball. It's very small, and the rows of the metallic atoms are very big like basketballs. The ping pong ball can move in and out of the basketball lattice very easily."
