This is a periodic table with atomic radius values mentioned on it.
The above atomic radii of the elements are the van der Waals radius and they are in picometers (pm).
What is Atomic radius on a periodic table?
The atomic radius is the distance from the center of the nucleus to the outermost orbit of an atom.
Atomic radius is measured by measuring the distance between the two atoms and then dividing the distance by 2, we get the atomic radius.
Atomic radius is measured in picometers (pm).
And, 1 pm = 10-12 meters.
