Why are metals sonorous? Which metal is the most sonorous?

metals are sonorous because electron bonding in metals is highly delocalized, due to their very low electronegativity. This means that when struck, the electron cloud moves extremely easily - there is very little energy dissipated. This allows the incoming kinetic energy to be easily propagated as a form of disequilibrium - a wave.

Now, it should be noted that this is not in all metals - it is in sheet metals, and they have to be of relatively low density. High-density metals will not as easily propagate the kinetic energy, due to additional atomic collisions damping the effect.

aluminium is the most sonorous metal.

hope it helpsss!!!!
