Web6 de abr. de 2024 · Immediately before 1913, the Rutherford model conceived of an atom as consisting of a tiny positively charged heavy core, called a nucleus, surrounded by light, planetary negative electrons revolving in circular orbits of arbitrary radii. Britannica Quiz Matter and More Quiz WebThe electrons in the atom must be orbiting around this central core, like planets around the sun, Rutherford proposed. Rutherford carried out a fairly simple calculation to find the size of the nucleus, and found it to be only about 1/100,000 the size of the atom. The atom was mostly empty space.
