Two animations are proposed to represent the particles in a solid metallic element.

Both animations show large particles marked $+$ in a regular, repeating three-dimensional arrangement.

In Animation A, small particles marked $-$ move only over the outside surface of the structure.

In Animation B, small particles marked $-$ can move through the spaces between the large particles in every layer and in any direction.

A student states that Animation A is accurate because its negative particles are moving.

Evaluate the student's statement. Refer to the particles represented and explain how the bonding holds the structure together.
