there are 2 electrons in the inner shell of a hydrogen atom.
Two electrons will fill a hydrogen's outer, or valence, shell.
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer 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.
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.
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
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
Beryllium like every other element excluding hydrogen has 2 electrons in its first shell.
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
2, there is always 2 in the inner shell.
The innermost shell of any atom bigger than hydrogen (H) will contain 2 electrons.

Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Carbon has two electrons in its inner shell and four in its outer shell.
Two electrons will fill a hydrogen's outer, or valence, shell.
