WebBYU-Idaho) Atoms are characterized by the number of protons found in their nuclei. The number of protons in the nucleus is referred to as the atomic number, and this number identifies the element. For example, all atoms with six protons are carbon (C) atoms, and all atoms with 79 protons are gold (Au) atoms. U Different elements have different ...

The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules. 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 diamondbacks vs blue jays
