Question

How does the composition of a water molecule affect its charge? It makes the molecule a negative ion. It makes the molecule a positive ion. It makes the molecule polar. It makes the molecule nonpolar.

Answer 1

The composition of a water ion causes it to be a polar molecule. This polarity is due to the more electronegative oxygen holding the electrons from its bond with hydrogen closer to itself. This induces a negative dipole on the oxygen and a positive dipole on the hydrogens. Combined, the dipole charges of water molecules allow them to hydrogen bond to each other.

Answer 2

Answer: The correct answer is it makes the molecule polar.

Step-by-step explanation:

An ion is formed when atom looses or gain electron.

If an atom gains electrons, it will carry negative charge and form an anion.

If an atom looses electrons, it will carry positive charge and forms a cation.

A polar compound is defined as the compound which is formed whenever there is difference in the electronegativity values between the elements.

A non-polar compound is defined as the compound which is formed when there is no difference in the electronegativity values between the elements.

Chemical formula for water is
`H_2O`. It is formed by the combination of hydrogen and oxygen atoms.

Oxygen is more electronegative atom than hydrogen atom and thus, oxygen atom will carry partial negative charge on it and hydrogen will carry partial positive charge on it. Thus, creating a dipole.

Hence, the correct answer is it makes the molecule polar.
