It can be determined by the number of electrons in realitivity with its other physical and chemical properties, if the bond is ionic or covalent, the electronegativity, atomic size, and conductivity.
Chlorine can form both positive and negative ions. As an element, chlorine typically forms a negative ion (Cl^-) by gaining one electron to achieve a stable electron configuration. However, in certain compounds, chlorine can also form a positive ion (Cl^+) by losing an electron.
Silver nitrate (AgNO3) contains a positive silver ion (Ag+) and a negative nitrate ion (NO3-). Silver ion is positively charged because it has lost one electron, while the nitrate ion is negatively charged due to its structure.
The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.
Sodium will be positive. Check your periodic table; all those elements on the left will always be positive ions.
The chemical formula of calcium chloride is CaCl2. CaCl2------------Ca2+ + 2Cl-
Na is positive ion,Cl is negative ion
it is a negative and positve ion sweg
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.
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
The ion acetate is negative.
Sodium chloride is very useful. Sodium ion is the positive ion.
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
