The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
carbon has totally six electrons. Out of these, four electrons are in the valence shell or the outer most shell.
Oxygen, with a electron number of 8 there are two electrons on the first orbit ring and six an the outer ring(shell) those are the valence electrons
0. All electrons will pair if there is an even number
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.
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.
Elements in group VIA (6A) also called group 16.
The valency of an element indicates the way it will react in a chemical reaction. For example, oxygen has six outer electrons and only needs eight electrons to have a complete outer shell. It can either lose six electrons or gain two electrons. It is easier for an oxygen atom to gain two more electrons and therefore its valency is 2.

six
All these elements have six electrons in the outer shell.
The basic Carbon atom has six protons and six electrons
Sulfur has sixteen electrons total, two in the inner shell, eight in the middle, and six in the outer. This means that it would have six valence electrons.
An Atom. An atom contains protons , neutrons and electrons. The number of protons in an atom gives it its characteristics. e.g. Hydrogen has ONE proton. Carbon has SIX protons. et seq/.
carbon has totally six electrons. Out of these, four electrons are in the valence shell or the outer most shell.
3d^6 Six electrons in the outer shell.
The element is carbon and the isotope is 6C14
