The amount of dissolution of rare gases in the primordial atmosphere into the molten earth material was determined considering that the gases escaped from the effects of strong solar wind and radiation. The quantity of the dissolved gases is strongly dependent on the grain opacity of the atmosphere; however, their isotopic ratio and relative abundance are independent of the opacity and are approximately equal to the present solar values. It is concluded that a significant amount of neon with the nearly solar isotopic ratio found in present mantle material would indicate that the proto-earth was once surrounded by the primordial atmosphere.
