Two.
Germanium has 18 inner shell electrons.
there are 2 electrons in the inner shell of a hydrogen atom.
In nitrogen, the inner shell consists of two electrons, which fill the 1s orbital.
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Cl is in the 17 group. It is in the 3rd period. It has 3 energy levels.
Since Helium is a noble gas meaning it is stable, and the fact that it has one shell, it has 2 shells in its inner-most shell.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
In a sodium atom, there are 2 electrons in the innermost shell. The first shell can hold a maximum of 2 electrons. Sodium has an electron configuration of 2-8-1, so the inner shell contains 2 electrons.
No it doesn't... Aluminum has 3 extra electrons in the outer shell
it takes 8 electrons for the second shell to be considered full
2 electrons in the K shell and 8 electrons in the L shell
the first shell of electrons has only 2 spaces in it before it is full whereas the 2nd shell has 8 electrons in it to be full.
