Chemists ordinarilyworkwith weighable quantities ofelementsandcompounds. For example, in the iron-sulfur equation the symbol Fe represents 55.845 grams of iron, S represents 32.066 grams of sulfur, and FeS represents 87.911 grams of iron sulfide. Because matter is not created or destroyed in a ch...
respectively. The symbol for iron is Fe, from its original Latin nameferrum. The fundamental principle of thescienceofchemistryis that the atoms of different elements can combine with one another to form chemical compounds.Methane, for example, which is formed from the elements carbon and hydrogen...

In the formulas of ionic compounds, simple ions are represented by thechemical symbolfor the element: Cl means Cl−, Na means Na+, and so on. When individual ions are shown, however, the charge is always included. Thus, the formula of potassium bromide is given as KBr, but, when the...
Alkaline earth metals produce ionic hydrides (originally called hydrogenides) with the general formula MH₂ (where the symbol M stands for an alkaline earth metal). Beyond the formation of these hydrides, they are also molecular solids, having a high melting and boiling point, due to the stre...
