How many more valence electrons does oxygen need to have a full outer?
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
How many valence positions does oxygen have for bonding?
Oxygen has 2 valence positions for bonding, allowing it to form up to 2 covalent bonds.
If potassium has a valence of 1 and oxygen has a valence of 2 the formula for potassium oxide is?
The formula for potassium oxide would be K2O. This is because potassium has a valence of 1 and oxygen has a valence of 2. To balance the charges, you need two potassium ions (each with a charge of +1) for every oxygen ion (with a charge of -2).
What gives magnesium and oxygen?
Magnesium = Mg+2 Oxygen = O-2 (Mg+2)+(O-2) = MgO = Magnesium Oxide so the formula for oxygen + magnesium - oxygen + magnesium oxide
What electrons are in oxygen valence?
An oxygen atom has two valence electrons.
