Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What charge does water (H2O) have?
A
Positive
B
Negative
C
Neutral
D
Positive and negative
Explanation: 

Detailed explanation-1: -Even though the covalent bond between each hydrogen and oxygen in water is polar, water molecules are electrically neutral molecules in their overall structure, as previously stated. There are 10 protons and ten electrons in each water molecule, providing a net charge of zero.

Detailed explanation-2: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).

Detailed explanation-3: -Water molecules are neutral. Be sure students realize that no protons or electrons are gained or lost. The water molecule has a total of 10 protons and 10 electrons (8 from the oxygen atom and 1 from each of the two hydrogen atoms). Since it has the same number of protons and electrons, the water molecule is neutral.
