Question
Which of the following statements about metallic bonding is true?Statement 1: In metallic bonding, the metal ion is positively charged and the delocalised electrons are negatively 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.Statement 1 and 3 onlyAll of the statementsStatement 1 onlyStatement 2 and 3 only
Solution
The correct answer is "Statement 1 and 3 only".
Here's why:
Statement 1: This is true. In metallic bonding, the metal atoms lose their outer electrons to become positively charged ions. These electrons become delocalised, meaning they are free to move throughout the entire metal structure, and they are negatively charged.
Statement 2: This is false. In metallic bonding, there is an attraction, not a repulsion, between the positively charged metal ions and the negatively charged delocalised electrons. This attraction holds the metal ions together in a lattice structure.
Statement 3: This is true. The sharing of the delocalised electrons between the metal ions results in a 'sea' of electrons, which creates a strong bond between the ions, making the metal strong.
