Several discoveries expanded the understanding of atoms. In 1913, Frederick Soddy described isotopes, which were forms of an atom of one element that contained different numbers of neutrons. Neutrons were … WebThe magnetic field deflected the electrons into circular paths of known radius (r). He could then calculate the charge-to-mass ratio (e/m) of the electron. e/m = 2V/ (B²r²) In 1906, Robert Millikan's famous oil drop experiment gave the charge on an electron. Only then did it become possible to calculate the mass of an electron. 1 comment can rebonding be done on henna hair
