A water molecule contains two hydrogen atoms and one oxygen atom. Which of the following statements about water molecules is true?
A. All of the atoms have a positive charge.
B. All of the atoms have a negative charge.
C. The oxygen atom is positively charged and the hydrogen atoms are negatively charged.
D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged.

D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged.

Explanation:

A water molecule is consists of two hydrogen bonds and one oxygen bond. The hydrogen and oxygen atoms share unequal electrons to form covalent bonds.

Due to unequal sharing of electrons oxygen atoms attracts electrons more strongly than the hydrogen atoms and oxygen gains a slightly negative charge and hydrogen atom gains slightly positive charge.

Hence, the correct option is "D. The oxygen atom is negatively charged and the hydrogen atoms are positively charged."
