Water is a polar molecule. What does that mean? A. It is a molecule with too many protons
B. it is a molecule with identical charges on opposite ends
C. it is a molecule with no charge
D. it is a molecule with opposite charges on opposite ends

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.

The answer is b hope this
