Determine whether the ion contains more than one element (e.g., the sulfate ion). If so, look up its name in the table under the Resources section below. Each name has a symbol that corresponds to it. Sulfate, for example, is SO4 -2 (with the -2 as a superscript and the 4 as ...
More traditional, less standardized names still linger in chemistry, however. For example, many fluoride rinses list stannous fluoride as an ingredient. Stannous refers to tin(II), so the chemical formula for stannous fluoride is SnF2. Other commonly used nonstandard names include ferric [iron(III...

Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn’t actually much to work out. But when elements l...

Also, I want everybody to pay attention: memorize the next paragraph. You hear things like this: “Business are suffering because of coronadoom”. NO! NO! NO! We suffered because of thegovernment reactionto coronadoom. Not because of the bug. Do not repeat this error, and call it out ...
Transition metal ions can combine with other types of atoms to form positively or negatively charged molecular complexes. An example of such a complex is the permanganate ion, MnO4–. Oxygen has an oxidation state or charge of –2, and so the four oxygen atoms add up to a charge of –8...
