In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
First shell contains atmost two electrons. The formula is 2n. where n is the no. of shell u want to calculate its capacity of no of electrons..thanku

It depends what electronic state it's found in, but in it's ground state (natural form) it has two electrons in the first shell, eight in the second and none in the third. This is because it has an atomic number of 10. 2+8 = 10.
The H+ ion has no electrons.
there are two electrons the first shell hold

Two electrons can fit in the first shell

There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
In the first shell of oxygen, there are 2 electrons, and in the second shell, there are 6 electrons. Oxygen has 8 electrons in total, with 2 of them in the first shell and the remaining 6 in the second shell.
Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
Beryllium like every other element excluding hydrogen has 2 electrons in its first 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.

Carbon has 2 electrons in it's first electron shell. All elements except hydrogen do.
The first shell of an atom can hold a maximum of 2 electrons. Since sodium has an atomic number of 11, the first shell will be filled with 2 electrons, and the remaining 9 electrons will go into the second shell.
