No. Ionic bonds are ionic, in which the difference of electronegativities between the atoms forming the bond are greater than 1.7. Nonpolar bonds are covalent bonds in which the difference of electronegativities of the atoms forming the bond is less than 0.5.
No, it is non-polar.
Polar
Polar covalent bonds between O and H
Hydrogen
Magnesium oxide has ionic bonds between magnesium and oxide ions.
No, it is non-polar.
Polar
It has polar bonds. It is classified as an ionic molecule. It will dissolve in a polar substance, such as water.
Ammonium ion is polar due to the ionic bonds present in the polyatomic ion.
Ionic bonds, Covalent bonds, Hydrogen bonds, Polar Covalent bonds, Non-Polar Covalent bonds, and Metallic bonds.
Polar covalent bonds between O and H
Hydrogen
NaCl is ionic, and polar/non-polar usually refers to covalent bonds. So, while it is polar in a sense (there are + and - parts) it is really ionic. It is, however, soluble in polar liquids, such a water.
Magnesium oxide has ionic bonds between magnesium and oxide ions.
Calcium sulfate has ionic bonds.
if the molecule is symmetrical, then it is nonpolar. if it is NOT symmetrical, it is polar. Ionic bonds form between a metal and a nonmetal.
MgBr2 is ionic, and so would be considered polar.
