Electron.

From plastic rod to metal sphere.

Explanation:

The charged plastic rod is negatively charged, which means it contains excess electrons.

After they touch each other, the plastic rod now has a more positive value.

Since the sphere is a metal sphere, it is able to conduct the flow of electrons.

Hence, the plastic rod has given off some of its electrons to the metal sphere.
