Sulphur.
What element has 2 electrons in the first shell and 8 in the second and 6 in the third
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
There are two electrons in the first shell of neon. Its complete electronic configuration is 2,8
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.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.

Sulfur
What element has 2 electrons in the first shell and 8 in the second and 6 in the third
There should be seven in the second shell and two in the first. The element in question is fluorine, which has the atomic number 9, the same as the number of its protons and electrons.
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
The answer is Sulphur
There are two electrons in the first shell of neon. Its complete electronic configuration is 2,8
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.
It is Oxygen. Because Oxygen has the atomic no. - 8. Which means that 2 electrons can accommodate in the inner shell and the rest of the electrons (6 electrons) are in the out shell.
