Electric charge is a fundamental property of matter. Its symbol is Q or q. Two Types of Charge Charge comes in two varieties: positive and negative: positive charge (+q) is a property of protons; negative charge (-q) is a property of electrons. The charge on the proton is identical ...
Also found in: Thesaurus, Medical, Encyclopedia. i·on (ī′ŏn′, ī′ən) n. An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. [Greek ion, something that goes, neuter present participle of ienai, to go; see ei-...
The carbon atom may be joined to each oxygen atom via single bonds (carbon = +2, oxygens = -1 each, formal charge = 0) Each possibility results in a formal charge of zero, but the first choice is the best one because it predicts no charge in the molecule. This is more stable and...

Ionic compounds are electrically neutral, because the total number of positive charges and the total number of negative charges are always equal. Considering the chemical elements, the highest tendency to form ionic compounds exists in the least electronegative metals and the most electronegative non...
