Answer:
of different elements with different electronegativities
Explanation:
A molecule containing two atoms "of different elements with different electronegativities"
A polar covalent bond exists when two different atoms (non-metals) with different electronegativities are able to share their electrons in a covalent bond.
Some examples of polar covalent bonds are seen in:
1. Ammonia(NH3): The polar covalent bonds exists between the nitrogen and hydrogen atoms.
2. Water(H2O): The polar covalent bond exists between hydrogen and oxygen. The oxygen molecule has a net negative charge while the hydrogen atoms have a net positive charge.
