Elements in group VIA (6A) also called group 16.
Oxygen typically exists as a divalent element because it has six valence electrons in its outer shell. By gaining two electrons, it can achieve a full valence shell, similar to the stable noble gases.
The outer valence shell of a sulfur atom contains a total of 6 electrons: two 3s electrons and four 3p electrons.
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
2 because if it was 8 it would be a full shell. 2 because if it was 8 it would be a full shell. 2 because if it was 8 it would have a full shell....
They all have 6 in its outer shell because they are all in the same group in the periodic table. Your VERY VERY welcome (:
All these elements have six electrons in the outer shell.
carbon has totally six electrons. Out of these, four electrons are in the valence shell or the outer most shell.

An oxygen atom has six (6) electrons in its outer shell.
An element that has two outer electrons is carbon. Carbon would not use the energy to gain six more electrons when it can easily get rid of the two outer electrons.

The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
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.
Sulfur has 6 outer shell electrons, as do all other atoms in column 16 of a wide form Periodic Table, in the usual chemical meaning. A physicist, especially a spectroscopist, might well consider only the 3p electrons of sulfur the outer shell, since the 3s electrons have a detectably lower energy level. On that view, sulfur would contain 4 outer shell electrons.
Sulfur can borrow up to six electrons to complete its octet and achieve stability. This is because sulfur has six valence electrons in its outer shell.
