Static Electricity - Mission SE4 Detailed Help

A neutral metal sphere is touched by a negatively charged metal rod. During the process, electrons are transferred from the _____ to the _____ and the sphere acquires a _____ charge.

Charging by Conduction:
Charging by conduction (or contact) is the charging process that involves the touching of a charged object to a neutral object. Upon contact, the charged object conducts some of its excess charge to the neutral object so that both objects share (not necessarily equally) the excess charge. The charge is conducted by the movement of electrons. Electrons move from a negatively charged object to a neutral object or from a neutral object to a positively charged object. When the process is complete, both objects are charged with the same type of charge.
