Want this question answered?
there are 2 electrons in the inner shell of a hydrogen atom.
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 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.
they have 28 electrons and 14 electron shell. could you answer this what song is this from Gangnam Style Never do SEX! It is WRONG!

there are 2 electrons in the inner shell of a hydrogen atom.
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.
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.

Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Two.
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron

A bromine atom has seven electrons in its outermost 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.
