Chemical formulas for molecules
WebThe Chemical Formula identifies the elements that comprise the compound as well as the number of atoms of each element in the smallest unit of that compound, whether a molecule or a formula unit. Knowing the element names and a few fundamental rules helps us to name simple compounds given a chemical formula. Web(a) Several elements naturally exist as diatomic molecules, in which two atoms (E) are joined by one or more covalent bonds to form a molecule with the general formula E 2. (b) A few elements naturally exist as polyatomic molecules, which contain more than two atoms.
