Ionic formulas balance the total positive and negative charges. Ionic compounds have a simple system of naming. Groups of atoms can have an overall charge and make ionic compounds.

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. Most metals become cations when they make ionic compounds.

Atoms that lose electrons acquire a positive charge as a result. Some atoms have nearly eight electrons in their valence shell, and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge.

You should find that copper has been reduced from +2 to +1; oxygen (in the gas) has been reduced from 0 to -2 (oxygen in the SiO 2 is unchanged); and three of the four sulfurs on the left-hand side have been oxidized from -2 to +4 (the other is unchanged).

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. These positively charged ions are called cations. In contrast, nonmetal atoms tend to gain electrons and thus become negatively charged. Negatively charged ions are called anions.

Ions form when atoms gain or lose electrons during electron transfer, resulting in positive or negative charges. These reactive ions can combine to create neutral compounds and are influenced by magnetic fields, as illustrated by the northern lights phenomenon.

It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species. Almost all of the transition metals have multiple potential oxidation states.
