The color of an ion often indicates the presence of transition metals in the compound. Transition metals can exhibit various colors due to the different ways they absorb and reflect light. This property of colored ions is often used in qualitative analysis and identifying specific metal ions in a solution.
Most transition metals form colored ion-complexes.
The notation for a potassium ion is K+. This indicates that the ion has a positive charge due to the loss of one electron.
Chloride ion: Cl-
The correct symbol for a cesium ion is Cs+. The superscript "+" indicates that the ion has a positive charge, meaning it has lost one electron.

Superscript indicates amount of charge on ion. It describes magnitude of charge.
The notation for a potassium ion is K+. This indicates that the ion has a positive charge due to the loss of one electron.
The symbol for a magnesium ion is Mg^2+. The superscript 2+ indicates that the magnesium ion has a positive charge of 2.
Chloride ion: Cl-
The correct symbol for a cesium ion is Cs+. The superscript "+" indicates that the ion has a positive charge, meaning it has lost one electron.
The positive oxidation number indicates the number of electrons an ion has lost, while the negative oxidation number indicates the number of electrons gained. The oxidation number provides information on the charge of the ion and its ability to form chemical bonds.
Elemental Oxygen combined with one Hydrogen - OH-
The transition metals tend to form colored compounds.
If the ending -ide is added to the name of an ion, it indicates that the ion is a negatively charged ion. This typically means that the ion has gained electrons to achieve a stable electronic configuration.
The sulfonate ion carries the chromophore in an acidic dye. When it attaches to a colored molecule and gives it a negative charge, it results in an acid dye.
