Question
Ionic bonding involves a transfer of electrons from a metal to a non-metal. The oppositely charged ions then combine because opposite charges attract electrostatic attraction. BUT the metal crystals which grew in our experiment were composed of metal atoms. Can you explain what holds the atoms in a piece of metal together. Include a diagram. Conclusion Based on your results, can you answer the Aim of the investigation? Include a list the metals in order from most reactive to least reactive. Remember, the more reactive metal displaced the less reactive metal from the solution.Explanation / Answer
The atoms present in the metals have metallic bonds in between them which holds them together .
The outermost electron shell / valence shell of each atom in the metal overlaps the other atoms , due to which these electrons continually move from one atom to the another , such that they are not part of a specific atom. These valence electrons are delocalised and wander freely throughout the metal crystal . The atoms that have left these electrons become positively charged and develop cohesive or binding force with the valence electrons , which holds them together in a crystal .
