Answer: -
Metals are ductile instead of brittle because they have flexible bonds.
Explanation: -
Metals have a property called ductility.
It is the ability of a metal to be drawn into wires.
Metals due to greater bond flexibility are more ductile.
The most ductile metal known to man is Gold. Metallic wires find many applications in modern machinery particularly.
Usually ductility and malleability go together.
Answer:
Explanation:\
Elastic energy is energy stored in an object when there is a temporary strain on it – like in a coiled spring or a stretched elastic band.
The energy is stored in the bonds between atoms. The bonds absorb energy as they are put under stress and release the energy as they relax (when the object returns to its original shape).
See the correct answer is b.)PbS
It is not good conductors of electricity or heat!
