Metallic bonding<span> is the force of attraction between valence electrons and the metal ions. It is the sharing of many detached electrons between many positive ions,
Hopefully this can help you understand

Use Force=Mass x Acceleration (newtons second law states force is directly proportional to the acceleration) so you can say that the force is negative and solve for Acceleration.
The basic relationship between wavelength

, frequency f and speed c of an electromagnetic wave is

where c is the speed of light. Substituting numbers, we find:
