Question
Using a diagram, explain how you would deduce that sodium chloride (NaCl) has an ionic structure.
Answer
To deduce that sodium chloride has an ionic structure, you would draw a diagram showing the transfer of an electron from a sodium atom to a chlorine atom. This results in the formation of Na⁺ and Cl⁻ ions, which are held together by strong electrostatic forces of attraction in a lattice structure.
Explanation
This question tests the student's ability to interpret diagrams and understand the characteristics of ionic compounds. The answer demonstrates knowledge of electron transfer and the resulting ionic structure.
Common mistake
Misinterpreting Diagrams
Students often misinterpret diagrams and conclude that a compound has an ionic structure when it actually has a covalent structure.
To fix this, students should carefully analyze the types of atoms involved and the bonding patterns shown in the diagrams, ensuring they recognize the characteristics of ionic versus covalent bonds.
