The excess electrons will move from the rod to the sphere and spread out.

The excess electrons will move from the rod to the sphere and stay close together.

Answer 1

When a negatively charged rod touches a metal sphere, the excess electrons will move from the rod to the sphere. This happens because the rod has a higher concentration of negative charge (excess electrons) compared to the initially neutral sphere. The electrons will spread out on the sphere due to the conductive nature of the metal, which allows for the redistribution of charge.

Therefore, the correct response is: The excess electrons will move from the rod to the sphere and spread out.
