No. Most of the time a metal and a nonmetal will form an ionic bond, but if the electronegativity difference is less than 1.6 (1.7 according to some), they could form a polar covalent bond. For example, beryllium chloride is a polar covalent compound because the electronegativity difference between the metal beryllium (Be) and the nonmetal chlorine (Cl) is 1.59.

The bond between F and Cl is a polar covalent bond. Fluorine is very electronegative and Cl is not as much. The difference is large enough to be considered polar.
No
A molecule can have a completely nonpolar covalent bond when two atoms of the same element form the bond.
A covalent bond due to the fact that they are both non-metals
By the equal sharing of electrons.
Yes, it is possible.
Yes, it is possible.
The bond between F and Cl is a polar covalent bond. Fluorine is very electronegative and Cl is not as much. The difference is large enough to be considered polar.
No
a) Must include a metal and a nonmetal b) Must be of different elements c) Are always of the same element d) Are always two metals Need Answer! :( D) Are always two metals. a) is for ionic compounds b) is for nonpolar covalent bonds c) same as nonpolar covalent bonds b) Must be of different elements:)
A molecule can have a completely nonpolar covalent bond when two atoms of the same element form the bond.
No. The difference in electronegativity is too great.
A covalent bond due to the fact that they are both non-metals
No. It can't.
By the equal sharing of electrons.
Sulfur hexafluoride has covalent bonds.
A non-polar covalent is one in which the electrons are shared equally.
