Question
What is the main difference between metallic conductivity and ionic conductivity in terms of the particles that move?
Answer
In metallic conductivity, delocalised electrons are the mobile charge carriers that move through the metal, allowing it to conduct electricity. In ionic conductivity, mobile ions are the charge carriers that move when the ionic compound is molten or dissolved in water.
Explanation
This answer clearly distinguishes between the two types of conductivity by identifying the specific particles involved in each process. The question tests the student's understanding of how different types of materials conduct electricity based on their structure and bonding.
Common mistake
Confusing Conductivity
Students often confuse metallic conductivity with ionic conductivity by stating that both involve the movement of electrons.
Clarify that metallic conductivity involves delocalised electrons as mobile charge carriers, while ionic conductivity involves the movement of mobile ions.
