Which statement correctly explains the molecular structure of water?
A) One oxygen and two hydrogen atoms are joined by a covalent bond.
B) One hydrogen and two oxygen atoms are joined by a covalent bond.
C) One oxygen and two hydrogen atoms are joined by an ionic bond.
The statement that correctly explains the molecular structure of water is A. One oxygen (O) and two hydrogen atoms (H2) are joined by a covalent bond. It cannot be ionic, since ionic bonds tend to be sold at room temperature.
A water molecule can form four hydrogen bonds by accepting two hydrogen atoms and donating two hydrogen atoms. Thus, One oxygen and two hydrogen atoms are joined by a covalent bond correctly explains the molecular structure of water
