The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po. If you would like to answer this yourself, just remember that the last digit of the group number is typically the number of valence electrons that you will have. The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.
The number of valence electrons equals an atoms main group number. Carbon is in group 4, therefore carbon has 4 valence electrons.
The outer valence shell of a sulfur atom contains a total of 6 electrons: two 3s electrons and four 3p electrons.
Both have six valance electrons. That is what the number at the top of their column means.
Atoms are always trying to get a full valence shell (outer shell of electrons) to make themselves stable. Hydrogen and Helium only need two electrons to do this, but the other elements need eight electrons in their valence shell. Atoms try to accomplish this in the easiest way possible, using single bonds. Sometimes, though, this doesn't work. A common example of double bonding is carbon dioxide. Carbon has four electrons in its valence shell and wants to have eight. That means it wants other atoms to share four electrons with it so it can fill its shell. The two oxygen atoms that it bonds to when it becomes carbon dioxide have six electrons in their valence shell and want eight. That means they want to share two electrons each with another atom so they can have eight electrons in their valence shell and be "full". The atoms work together, sharing electrons to fill each other's valence shells, and each of the two oxygens form a double bond with carbon. The carbon atom gets two electrons from each oxygen (four total) to add to its own four to make a total of eight electrons (a full valence shell). Each oxygen gets two electrons from the carbon atom to add to its own six, making a total of eight electrons (a full valence shell). Basically, atoms share more than one pair of electrons in double or triple bonds because it's the best way for them to fill their valence shell.
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.

carbon has totally six electrons. Out of these, four electrons are in the valence shell or the outer most shell.

it needs six more electrons to have a full outer valence 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
An unbonded oxygen atom has eight electrons, with six of the electrons located in the valence shell. Two of the valence electrons are unpaired, and therefore can undergo covalent bonding with other oxygen atoms or nonmetals (such as hydrogen).
Two oxygen atoms can form a double bond by sharing two pairs of valence electrons between them, resulting in the formation of an oxygen molecule (O2). This double bond allows both atoms to achieve a stable configuration with a full outer electron shell of eight electrons, following the octet rule.
