Webb3 dec. 2024 · the radius of an atom is about 0.1 nm (1 × 10-10 m) the radius of a nucleus (1 × 10-14 m) is less than \ (\frac {1} {10,000}\) of the radius of an atom. For comparison, … WebbWe know the approximate size of atoms since 1811, Amedeo Avogadro (1776-1856) estimated its size to 1 angstrom, i.e. 10-10 meter and one century later, in 1911 Ernest Rutherford (1871-1937) specifies, the structure of atoms, and gives a size the atomic nucleus of the order of 10-14 meters. One can say that the atoms are separated from …
