A fluoride ion is an atom with 9 protons in its nucleus, making it a fluorine atom. It is an “ion” because the number of electrons is not equal to the number of protons, which is also the reason for the “ide” suffix. More specifically, each fluoride ion has 10 electrons, giving...

The colour of oyster shells is a very diverse characteristic morphotype, forming intriguing vivid patterns both on the inside and outside of the shell. In the present study, we have identified for the first time, the presence of several porphyrins as constituents of the shell pigmentation of the...
A simple anion (obtained from a single atom) is named by taking the root of the parent element’s name and adding the suffix-ide. Thus, the F−ion is called fluoride, Br−is called bromide, S2−is calledsulfide, and so on. ...

In a fluoride mixture containing oxide, it is possible to follow in situ the dissolution of this oxide and to detect the formation of oxifluoride species in the melts or some precipitation from the melt. Because of the poor sensitivity of oxygen and the low natural abundance of the observable...

Examples of the reducing agent are stannous salts, i.e. salts of divalent tin ion (Sn++ ). Specific examples are stannous halides (e.g. stannous chloride, stannous fluoride), stannous sulfate, stannous nitrate, stannous acetate, stannous citrate, etc. Sn++ ion-bearing resins, e.g. ion-exc...
