there are two electrons in magnesiums outer shell, and 6 in oxygens. In magnesium oxide the electrons from Mg are donated in order to give both elements complete outer shells

What type of chemical reaction is magnesium oxide?
Magnesium Oxide is a compound, not a reaction. However if you are talking about making magnesium oxide from its individual elements, that would be a redox reaction. In this reaction, magnesium is going from a zero oxidation state to a +2 oxidation state. If you think of the acronym OIL RIG (Oxidation Is Lost Reduction Is Gained) Magnesium is being oxidized as it has lost two electrons. As well, the oxygen is gaining two electrons to have a -2 charge and is therefore being reduced hence the term redox.
Why is magnesium oxide not called magnesium dioxide as there are 2 oxygen atoms?
There is only one oxygen ion per magnesium oxide compound. Even though oxygen is a diatomic molecule, each atom in this O2 molecule has six electrons in its outer energy level. Magnesium has two electrons in its outer shell. Consequently, only one oxygen atom and one magnesium atom are needed to form the compound MgO, which is stable and unreactive. The following link has diagrams and perhaps a clearer explanation.
What happens if oxide atom becomes an oxygen atom?
Oxide is the ion form of oxygen. It forms when an oxygen atom gains an extra two electrons. So an oxide ion would become an oxygen atom by losing two electrons.
What is the value of oxide ion and phosphate ion?
Oxide - O2- electronic configuration of oxygen atom: 1s2, 2s2 2p4. electronic configuration of oxygen ion: 1s2, 2s2 2p6. phosphate - PO43-
Can oxygen have a negative charge?
By becoming an oxide ion, O=
An oxide ion is oxidized to an oxygen atom by what?
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
Can the proportions of magnesium and oxygen in magnesium oxide be changed?
No. Magnesium oxide, MgO, is a compound, which means it is a pure substance, in which the magnesium and oxygen are present in definite proportions, in this case 1:1. This is in accordance to the law of definite proportions, which states that every pure substance always contains the same elements combined in the same proportions by weight. Also, magnesium ions have a charge of 2+ and oxide ions have a charge of 2-, so that one magnesium ion combined with one oxide ion balances to an overall charge of zero.
Ion of oxygen?
Oxygen usually forms the oxide ion O2-

Magnesium oxide is an ionic compound represented by the formula unit?
MgO. Both the magnesium cation and the oxide anion are divalent, so that each ion neutralizes the charge of the other ion.
The anion formed from an oxygen called?
Oxide ion.
What are the ions and the correct formula for magnesium oxide?
the ions are 67 and one half since the molecular structuere
What ions are formed by oxygen and fluorine?
Oxygen forms the O2- oxide ion; fluorine the F- fluoride ion.
Does oxygen form ionic bonds?
Yes oxygen can form the oxide ion O2-, and the peroxide ion O22-
What is the value of oxide ion and phosphate ion?
Oxide - O2- electronic configuration of oxygen atom: 1s2, 2s2 2p4. electronic configuration of oxygen ion: 1s2, 2s2 2p6. phosphate - PO43-
