a metallic object is given a positive charge by induction, does the mass change (increase, decrease, same)? what if given a negative charge instead?

I think protons has more mass so mass increases and the opposite is true for electrons. Am I right?

    There will be a VERY small increase in mass of an object charged negatively, since electrons are added. Conversely, there will be a very small mass decrease for a positivly charged object, since electrons are removed. The changes may be too small to measure with available instruments, but they are there.
