Hello! Your answer would be againofelectronsand adecreaseinpositivecharge.
Contrary to how it sounds, reduction is actually a gain of electrons. It is part of a set of reactions known as a redox reaction, reduction being a gain of electrons and oxidation being a loss.
With the gain of electrons, the element wouldbecome more negativeas electrons bring with them a negative charge. Therefore, this would decrease the positive charge.
