Question

This image shows the ionic bond between sodium and chloride in NaCl (table salt), and the covalent bond between oxygen and hydrogen in H2O (water.) How are the bonds different?molecular structure
Question 3 options:


The hydrogen transfers its electrons to oxygen in water; sodium and chlorine in salt share their electrons.



The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.



The oxygen transfers its electrons to hydrogen in water; sodium and chlorine in salt share their electrons.

Answer 1

Answer:

B. The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.

Explanation:

The bonds between sodium and chloride in NaCl (table salt), and oxygen and hydrogen in water are different as sodium and chloride in NaCl have ionic bond and oxygen and hydrogen in water have the covalent bond.

Sodium transfers an electron to chlorine in sodium chloride (NaCl), so that they both have full outer shell and form ionic bonds. sodium and chloride ions exerts electrostatic force on each other and bond together with ionic bonds.

The hydrogen and oxygen atoms in water have covalent bonds because they are bonded by sharing electrons. Both hydrogen and oxygen atoms share unequal electrons with each other and form V-shaped water molecule.

Hence, the correct answer is "B."
