WebRutherford’s scattering experiment is also known as the gold foil experiment. This experiment disproved the plum pudding model of J.J. Thomson. In a gold foil experiment, high-energy alpha particles are made to strike a thin gold foil. The scattered alph… WebMar 24, 2016 · Now, it is a fact that the atomic mass of gold is 196.97 g*mol^-1, roughly close to 197. Because the atomic mass is 197 "amu", there must be 197-79= 118 " neutrons", massive, neutrally charged "nucular" particles. Atomic mass is to a first (and second) approximation, the sum of the protons and neutrons (there will be a mixture of … WebGiven that the only naturally occurring isotope of gold is 197Au,what is its isotopic mass?
