After accepting electrons, it reduces to neutral atoms with negatively charged ions, such as O2, Cl2, O3, etc.;

Positively charged atoms, after accepting electrons, are reduced to negatively charged ions. For example, under alkaline conditions, CL+ in hypochlorite OCl- and Cl4+ in chlorine dioxide in bleaching agents, sodium hypochlorite, etc. Accept electrons to be reduced to Cl-;

Atoms with high positive charges are reduced to atoms with low positive charges after accepting electrons. For example, Fe3+ in ferric chloride and Mn7+ in potassium permanganate are reduced to Fe2+ and Mn2+ after accepting electrons.
