Question
Which of the following statements about metallic bonding is true?Statement 1: In metallic bonding, the metal ion is negatively charged and the delocalised electrons are positively charged.Statement 2: In metallic bonding, there is a repulsion between the metal ion and the delocalised electrons.Statement 3: The sharing of the delocalised electrons between the metal ions causes the metallic bond to be strong.None of the statementsStatement 2 and 3 onlyStatement 1 onlyStatement 3 only
Solution
The correct answer is "Statement 3 only".
Here's why:
Statement 1 is incorrect. In metallic bonding, the metal ions are positively charged, not negatively charged. The delocalised electrons are negatively charged, not positively charged.
Statement 2 is also incorrect. In metallic bonding, there is an attraction, not a repulsion, between the metal ions and the delocalised electrons.
Statement 3 is correct. The sharing of the delocalised electrons between the metal ions does indeed cause the metallic bond to be strong. This is what gives metals their characteristic properties such as high melting and boiling points, and good electrical conductivity.
