No, the triple N-N bonds must be all covalent because there is no difference in elecron attraction (electro-negativity) between the one and the other N atom
(All elemental atoms of one kind have the same chemical properties, only the mass can be different (in the case of isotopes)).
Nitrogen will form a non polar bond to another nitrogen, a polar bond to other atoms with different electronegativity. In NH3 N is the most electronegative, in NF3 it is F that is the most electronegative.
Polar covalent bond
The electronegativities of nitrogen and fluorine are considerably different. Therefore they make a polar covalent bond.

A covalent bond is only polar if there is a difference in electronegativity between the two atoms. Since the two oxygen atoms in an O2 molecule are identical there is no such difference.
Nitrogen will form a non polar bond to another nitrogen, a polar bond to other atoms with different electronegativity. In NH3 N is the most electronegative, in NF3 it is F that is the most electronegative.
it forms a triple bond
Polar covalent bond
polar covalent
it forms a triple bond
Nitrogen is both an element and a molecule. In molecular form, Nitrogen forms a binary molecule N2 with a triple bond between the two Nitrogen atoms.
No. Fluorine is an element. Two atoms of the same element will not form a polar bond because there is no difference in electronegativity.
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
Non Polar Bond
A nitrogen atom contains three valence electrons so a nitrogen molecule N2 will form a triple covalent bond.
The electronegativities of nitrogen and fluorine are considerably different. Therefore they make a polar covalent bond.
