WebRutherford used his data to find the charge of the gold target nucleus. Further experiments to find the charge of Cu, Ag and Pt foils gave: So the electric charge on a nucleus is given by the atomic number × e, i.e. Z e. With one exception (hydrogen, H-1), Z is always less than the atomic mass number. WebRutherford's gold foil experiment provided evidence that the plum pudding model of the atom was inaccurate. The formula for measuring the size of the nucleus was developed based on Rutherford's gold foil experiment id given as R= R 0 A 1/3. The mass of a nucleus is divided by the total volume to determine its density (ρ).

Web5 Apr 2024 · The hydrogen nucleus is the smallest (1.75 * 10-15 m) since it has a single proton. The size of nucleus is of the order of 1.2 * 10-15 m, and the nuclear radii range from 1 - 10 * 10-15 m. Some nucleus is spherical while some are flattened and have deformed shapes. The formula to measure the size of nucleus is: R = R0A1/3. WebRutherford directed beams of alpha particles (which are the nuclei of helium atoms and hence positively charged) at thin gold foil to test this model and noted how the alpha particles scattered from the foil. Rutherford made 3 observations: Most of the fast, highly charged alpha particles went whizzing straight through undeflected.
