A. Nitrogen has a greater number of isotopes than hydrogen.
B. Nitrogen has a greater electronegativity value than hydrogen.
C. Nitrogen has a mass number that is 14 times that of hydrogen.
D. Nitrogen has seven neutrons, but hydrogen does not have any neutrons.

Respuesta :

Answer:

Option B

Explanation:

As nitrogen is more electronegative than hydrogen atom, it attracts the electronic cloud towards it center. This results in poles formation that is partial positive charge on hydrogen and partial negative charge on hydrogen atom. Hence, it makes polar polar covalent bond.
