there are 2 electrons in the inner shell of a hydrogen atom.
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 sodium atom (Na) has 11 electrons. The electron configuration of sodium is 2-8-1. The third noble gas shell is the second energy level or shell, which can hold a maximum of 8 electrons. Therefore, the number of electrons in the third noble gas shell of sodium is 1.
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.
Sodium has two inner shells. The first inner shell can hold up to 2 electrons, while the second inner shell can hold up to 8 electrons. Sodium's electron configuration is 2-8-1, with one electron in the outermost shell.
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.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
Cl is in the 17 group. It is in the 3rd period. It has 3 energy levels.
In sodium, the second shell (or energy level) can hold a maximum of 8 electrons. However, sodium only has 2 electrons in its second shell. Sodium has an atomic number of 11, so it has 11 electrons in total, with 2 in the first shell and 8 in the second 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.
