Detailed explanation-1: -Ions. Definition: An ion is an atom or molecule which has lost or gained one or more electrons, and carries a net electric charge. If the result is an atom with more electrons than protons, the ion is negatively charged.
Detailed explanation-2: -Oxidation is the process of losing an electrons, while reduction is the process of gaining them. Any chemical that causes another chemical to lose electrons (become oxidized) is called an oxidizing agent. Conversely, any chemical that causes another chemical to gain electrons is called a reducing agent. 1.
Detailed explanation-3: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.
