there are 2 electrons in the inner shell of a hydrogen atom.
Two electrons will fill a hydrogen's outer, or valence, shell.
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.
2 electrons in the K shell and 8 electrons in the L shell
Helium (He) and Calcium (Ca) both have 2 valence electrons.
The inner electron shell (also known as the s shell) can hold only two electrons. There are only two elements, hydrogen and helium, whose electrons all fit into the first shell.
Germanium has 18 inner shell electrons.
In nitrogen, the inner shell consists of two electrons, which fill the 1s orbital.
on the innermost shell of any element there is 2 electrons (except for Hydrogen, but that's a different story) so the answer would be 2
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Beryllium like every other element excluding hydrogen has 2 electrons in its first shell.
Cl is in the 17 group. It is in the 3rd period. It has 3 energy levels.
no electron is present in the outer most shell of hydrogen ion
Two electrons will fill a hydrogen's outer, or valence, shell.
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.

Two.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
