The atmosphere evolution of terrestrial planets from the origin of protoatmospheres throughout the most active period of a planet’s host star until the star’s activity decreased to moderate and quiet levels is discussed. The first protoatmosphere will be captured and accumulated hydrogen- and helium-rich gas envelopes from the nebula. Depending on the planetary formation time, the nebula dissipation time, the numbers of additional planets including gas giants in the system, the protoplanet’s gravity, its orbit location, and the host star’s radiation and plasma environment terrestrial planets may capture tens or even several hundreds of the Earth ocean equivalent amounts of hydrogen around its rocky core.
