Answer:
A polar bond
Step-by-step explanation:
- Ionic bond don't share but one atom accepts electron while the other gives away electron
- Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive
- A polar bond deals with the share of unequal electron (I.e. Covalent polar bond)
- A hydrogen bond is covalently bonded to highly electronegative elements of small atomic size
