WebExplain why the atomic radius of hydrogen is so much smaller that the atomic radius for potassium. For ionic radii, that means the atom or element has a CHARGE. Naturally, cations (+) are going to be smaller in size than their same neutral atom, and even much smaller than their anion (-) form. WebThere are several other ways ways to define radius for atoms and ions. Follow the appropriate hyperlinks for literature references and definitions of each type of radius. All values of radii are given in picometres (pm). Conversion factors are: 1 pm = 1 × 10 ‑12 metre (meter) 100 pm = 1 Ångstrom 1000 pm = 1 nanometre (nm, nanometer) Neutral radii
