No such substance as magnesium **DI**oxide.
It is magnesium oxide.
The chemial formula is MgO.
MgO is an IONIC bons. Magnesium metal ionises two electrons
Hence
Mg(s) = Mg^(2+) + 2e^(-)
Oxygen has an electron affinity for two electrons.
Hence
O+ 2e^(-) = O^(2-)
Since the charges balance and are opposite , the two ionis come together by electrostatic attraction, just like the N & S poles of a magnet. They do NOT share electrons.
Mg^(2+) + O^(2-) = MgO(s)
Dioxide is typically covalent, meaning it forms through the sharing of electrons between atoms. Ionic compounds involve the transfer of electrons, which is not the case for dioxide molecules.
No, MgCl2 is not covalent. It is an ionic compound formed by the transfer of electrons from magnesium to chlorine atoms. Magnesium loses two electrons and each chlorine gains one electron to form the ionic bond.
It depends on the rule you use to classify it. Magnesium Sulfide is ionic, if using the metal-nonmetal rule. It is polar covalent, if using the 1.7 electronegativity difference rule. Both these rules are generalizations.
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.

Magnesium chloride has an ionic bond.
no. it only has ionic as far as i know.
Ionic
Magnesium oxide is an ionic compound, not a covalent compound. It is formed through the transfer of electrons from magnesium to oxygen, resulting in the formation of ionic bonds between the two elements.
covalent
Dioxide is typically covalent, meaning it forms through the sharing of electrons between atoms. Ionic compounds involve the transfer of electrons, which is not the case for dioxide molecules.
