The substance that loses the electrons is ... The process in which a substance loses an eleIn general, metals will lose electrons to become a pos Oxidizing Agent Definition. An oxidizing agent is a chemical substance which causes another chemical species to lose electrons. Oxidation means the loss of electrons, the loss of a hydrogen atom, or the addition of an oxygen atom. The oxidizing agent has the ability to accept or transfer those electrons. Ionic bonding is the type of bonding that holds salts together An oxidation-reduction (redox) reaction involves the transfer of electrons between two species. In such reactions, one species loses electrons (is oxidized) while the other gains electrons (is reduced). To determine whether a species is an oxidizing agent or a reducing agent, we need to look at its ability to accept or donate electrons. May 22, 2023 · Oxidation is a chemical reKey Takeaway.
