4. What is meant by the fact that water is a "polar" molecule?
Ksju [112]

Hello!

A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.

Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.

Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.

Hope this helps!
