Atomic radii and Na & Cl

  1. May 8, 2015 #1
    Atomic radii of Na is much bigger than of Cl yet the drawings in Chemistry books often depict Na atoms smaller than Cl. Is there a reason for that??

    Are you sure these drawings don't use ionic radii?

    Oopps, you're right, they're ionic :)

    thank you.
