Fluorine's electronegativity is 3.98. The difference between two fluorine atoms is 0, so the bond between two fluorine atoms is nonpolar covalent.
Nonpolar covalent.
The bond between carbon and fluorine is covalent. Carbon only forms covalent bonds, in all cases.
Covalent
Rule of thumb answer is covalent bonds form between non metal elements.
covalent
Ionic bond, as the difference in electronegativity between calcium and fluorine is over 1.7
They can be expected to form ionic bonds.
ionic bonds
Fluorine atoms have a covalent bond between each other to form a covalent molecule. Fluorine bonded to a metal will have ionic bonds. Fluorine bonded to a non-meatl will have polar covalent bonding.
Nonpolar covalent.
The bond between carbon and fluorine is covalent. Carbon only forms covalent bonds, in all cases.
A covalent bond would form between these atoms. Covalent bonds involve atoms sharing electrons.
Covalent
fluorine and silicon form a perdominately ionic bond. fluorine is a nonmetal and silicon is a metal.
Rule of thumb answer is covalent bonds form between non metal elements.
Fluorine most often forms ionic bonds with other elements.
