The formula to calculate the effective nuclear charge on a valence electron in an oxygen atom is Zeff Z - S, where Z is the atomic number of the element (in this case, oxygen with an atomic number of 8) and S is the shielding constant.
The Lewis dot structure for carbon monoxide (CO) consists of a carbon atom with two valence electrons and an oxygen atom with six valence electrons. The carbon atom shares one electron with the oxygen atom, forming a double bond. The remaining electron on the oxygen atom is unpaired.
Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
The electron dot structure for OH (hydroxide ion) has one oxygen atom in the center with one hydrogen atom attached through a single bond. The oxygen has six valence electrons (group 16) and the hydrogen contributes one valence electron, resulting in a total of 7 valence electrons in the structure.
The outermost electrons are called VALENCE electrons.

Oxygen has six valence electrons.
A neutral oxygen atom has six valence electrons.

The magnesium has 2 valence electron while the oxygen misses 2 electron to complete its octet. An atom is always more stable when it has 8 valence electrons. The magnesium will create an ionic bond with the oxygen by giving its 2 electrons to form Magnesium Oxide, MgO.

The outermost electrons are called VALENCE electrons.
To calculate the number of valence electrons in an atom, you look at the group number of the element on the periodic table. The group number tells you how many valence electrons the atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
Oxygen as 6 valence electrons.
C2H6O, also known as ethanol, has 20 valence electrons. Each carbon atom contributes 4 valence electrons, each hydrogen atom contributes 1 valence electron, and the oxygen atom contributes 6 valence electrons.
