| The function of pyrazolone derivative in silver halide photographic paper is as a filter to prevent halation and irradiation. |
| The halide retains the electron pair of the carbon-halogen bond when it leaves. |
| After processing in this bath, the film is clear where the developed silver was and white where the remaining silver halide is. |
| For instance, electronegativities in the halide sequence fluorine, chlorine, bromine, and iodine decrease from fluorine through iodine. |
| It is not possible to overdevelop, and it is important to completely develop the remaining silver halide. |
| When a halogen combines with another element, the resulting compound is called a halide. |
