Question:
The radius of a gold atom is 144 pm. How many gold atoms would have to be laid side by side to span a distance of 4.40 mm?
Atomic Radius:
The atomic radius of an atom can be defined as the distance of the outermost shell of the atom from the nucleus. The atomic diameter of the atom can be considered as the twice of the atomic radius.
