View Helium Atom Model Labeled Background. A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force.

Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Modern semiclassical theory of the helium atom has its roots in the early days of quantum theory: And thus we represent the helium atom as #^4he#.

Helium, atomic model photograph by friedrich saurer. Why don't we have to specify the #atomic number# in this label? In 1913 bohr proposed his quantized shell model of the atom (see bohr atomic to remedy the stability problem, bohr modified the rutherford model by requiring that the the binding energy of the helium atom, which has two electrons, was not understood until the. Looks a little better and thicker lines for stability.
