Why are iron and sulphur classified as an elements?
Iron is Element 26 in the periodic table and a transition metal. Sulfur is Element 16 in the periodic table and is a non-metal. Elements at particles, or more properly molecules of a substance that cannot be broken down into further substances. (For this purpose, you need not worry about subatomic particles.) The atomic number is based on the number of protons in the nucleus of the atom in question, therefore 26 protons is Iron, and therefore it is 26th in the table. Compounds are substances made out of two or more elements, for example: Iron(II) sulfate (FeSO4) is used in water purification and sewage treatment systems, as a catalyst in the production of ammonia, as an ingredient in fertiliser and herbicide, as an additive in animal feed, in wood preservative and as an additive to flour to increase iron levels. This compound contains. at a molecular level one iron atom, Fe, one Sulfur atom, S, and four oxygen atoms, O4. As an aside, it was decided some years ago, to rationalise the sp
