Helium atom Helium atom 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. Unlike for hydrogen, a closed-form solution to the Schrödinger equation for the helium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and wavefunction of the atom. The quantum mechanical description of the helium atom is of special interest, because
Mister Atom Mister Atom Mister Atom is a fictional comic book supervillain, a radioactive robot who is regularly seen as an enemy of Captain Marvel. Mister Atom first appeared in "Captain Marvel Adventures" #78 and was created by Otto Binder and C. C. Beck. Mister Atom was created by Dr. Charles Langley in a story in "Captain Marvel Adventures" #78. His body was constructed first, and then Langley charged the robot with radioactive energy. The spark that gave the robot life also ended the life of his creator. Super-charged with a nuclear reactor and armed with a deadly mind, Mister Atom went
