The hydrogen shell refers to a layer of hydrogen gas that surrounds a star, particularly in the context of stellar evolution. In the case of massive stars, this hydrogen shell is often found outside the core and may undergo nuclear fusion as the star evolves. The term is commonly used when discussing the structure of stars during different phases of their life cycle, especially in red giants and supergiants.

What is the shell called in a hydrogen atom And is this shell complete?

In a hydrogen atom, the only electron occupies the first energy level or shell, which is often referred to as the K shell. This shell can hold a maximum of two electrons, and since hydrogen has only one electron, the shell is not complete. Therefore, hydrogen is typically reactive, seeking to either gain or share an additional electron to achieve a full outer shell.
