In the electric charge.
Negative ions have an excess of electrons while positive ions have a deficiency of electrons.
Na is positive ion,Cl is negative ion
An ion is either a positive charged or a negative charged atom. Negative ions have one or more extra electrons, and positive ones have one or more electrons not there.
it is a negative and positve ion sweg
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
To become more stable: positive+negative=neutral. Neutral is more stable than positive and/or negative.
Zinc ion (cation) is positive.
negative
when an atom loose electron it become negative ion and when it gains electron it become positive ion
Sodium chloride is very useful. Sodium ion is the positive ion.
The ion acetate is negative.
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
