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.
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.
there are 2 electrons in the inner shell of a hydrogen atom.
hydrogen (H) and helium (He)
Two electrons will fill a hydrogen's outer, or valence, shell.
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.

Hydrogen has a shell of just 1 electron. 1s
there are 2 electrons in the inner shell of a hydrogen atom.
Hydrogen has one shell with only 1 electron on the valance shell.
K shell.
hydrogen (H) and helium (He)
Hydrogen only has one electron, which fills its only electron shell (the first shell).
no electron is present in the outer most shell of hydrogen ion
Hydrogen doesn't really have a valence shell. It has one electron only.
A substance with 1 electron in the valence shell is called a monovalent element, such as hydrogen or lithium. A substance with 2 electrons in the valence shell is called a divalent element, such as beryllium or magnesium.
All elements in the first period have 1 shell. That's hydrogen and helium.
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
