Electronegativity Difference
HF = 1.9 = ionic bond
HC = 0.4 = nonpolar covalent
HH = 0 = nonpolar covalent
HN = 0.9 = polar covalent
HN is the more polar bond. HF is not polar covalent, it is ionic.
Here H-F is most polar because F is the most electronegative atom.

Polar covalent bond between nitrogen and hydrogen atoms Polar covalent bond between nitrogen and hydrogen atoms.
Nitrogen bases bond by the help of covalent or hydrogen bonds
Carbon will form four covalent bonds, nitrogen will form three covalent bonds, oxygen will form two covalent bonds, and hydrogen will form one covalent bond. Click on the related link to see a diagram showing the structure of an amino acid.
maximum number of covalent bonds typically formed by fluorine is 1
Fluorine forms both ionic bonds and covalent bonds, the former being more common.
Fluorine and hydrogen
hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, and chlorine are all nonmetals. nonmetals form covalent bonds.
A hydrogen bond is weaker than a covalent bond.
Covalent bonds form molecules where ionic bonds form ionic lattices. Hydrogen bonds are a form of intermolecular bonds which are formed with the participation of polar hydrogen atoms which are attached to either nitrogen, oxygen or fluorine.
The bond between hydrogen and fluorine is not a covalent bond. When hydrogen bonds with oxygen, nitrogen, or fluorine, then it is called a hydrogen bond. Hydrogen bonds will be stronger than a regular covalent bond, so the electronegativity difference will be higher.
Polar covalent bond between nitrogen and hydrogen atoms Polar covalent bond between nitrogen and hydrogen atoms.
The bonds between nitrogen and hydrogen are covalent. They make several compounds including ammonia and hydrazine.
The bonds are hydrogen bonds.
Ionic and covalent bonds are both chemical bonds formed by either sharing or transferring electrons. Hydrogen bonds are technically not a kind of chemical bond but a kind of intermolecular attraction between polar molecules in which hydrogen is bonded to one of the very electronegative elements nitrogen, oxygen, or fluorine.
