The formula is 2n2 where n is the principal quantum number (the "shell" number). In this case the second shell has a principal quantum number of 2 so 2X 22 = 8
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.

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.
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
The first shell (K shell) can hold up to 2 electrons, the second shell (L shell) can hold up to 8 electrons, the third shell (M shell) can hold up to 18 electrons, and the fourth shell (N shell) can hold up to 32 electrons.
Carbon has 4 electrons on its second shell. This is calculated based on the maximum number of electrons that can occupy the second shell, which is 8.
The second electron shell can hold a maximum of 8 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.
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.
8 electrons
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
it takes 8 electrons for the second shell to be considered full
A fluorine atom has 7 electrons in total. In its second shell, fluorine will have a maximum of 8 electrons, but since it has 7 electrons already in the first shell, it will only have 1 electron in the second shell.
There 8 electrons in the second shell.

14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
