Consider two different hydrogen atmos. The electron in each atom is in an excited state. Is it possible for the electrons to have different energies but the same orbital angular momentum according to the Bohr model ? Two H atoms in the ground state collide inelastically. The maximum amount by which their combined kinetic energy [...]

Two H atoms in the ground state collide inelastically. The maximum amount by which their combined kinetic energy is reduced is Two H atoms in the ground state collide inelastically.
