Estimating the size of a molecule using oil. It would be wonderful if you could measure the size of a single atom, but atoms are so small that it cannot be done directly. Yet you can find the size of a molecule in a roundabout way and from that calculate the size of an atom. Lord Rayleigh (English physicist, 1842 to 1919.
The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.) Mass : Although it is very small, the nucleus is massive compared to the rest of the atom. Typically the nucleus contains more than 99.9% of the mass of the atom.
