Looking for English translators, majoring in chemistry.

The primitive atmosphere is formed by the decomposition and volatilization of minerals in the earth's crust at high temperature, and its main components may be nitrogen and carbon dioxide. Water vapor condenses to form a liquid ocean. Unlike other planets, our earth's atmosphere contains very rare oxygen. Almost all oxygen comes from photosynthesis. Under the action of solar energy, green plants convert carbon dioxide into required organic matter through photosynthesis (see topics JBOY3 and J6). The main free components of the ocean are ions that cannot form stable compounds. Many common elements, such as calcium and silicon, are dissolved in river water in the form of ions, and a large number of these elements are brought into the sea by rivers, but many of them are precipitated by inorganic or biological processes (see above). The other ions with high content (sodium, chlorine and magnesium ions) will form water-soluble compounds, which can only be decomposed by evaporation.
