Chemistry is said to be a subject mostly comprising of reactions along with formulas. We come across various chemical substances in our daily life. Some of the substances we use in our house such as the staples present in the medicine cabinet comprise chemical substances. Chemical Formula in Chemistry is like a shorthand used to represent the elements in a compound. The Periodic Table has elements along with the symbols. These Chemical symbols are used for representing different individual elements like H is hydrogen, O for oxygen, Ca for calcium, Na for Sodium and so on. Molecular Formula : The molecular formula gives you the number of elements present in a compound.
These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name , and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances , and are generally more limited in power than chemical names and structural formulae. The simplest types of chemical formulae are called empirical formulas , which use letters and numbers indicating the numerical proportions of atoms of each type. Molecular formulae indicate the simple numbers of each type of atom in a molecule, with no information on structure.

The empirical and molecular formulas discussed in the preceding section are precise and informative, but they have some disadvantages. First, they are inconvenient for routine verbal communication. In such cases, it is necessary for the compounds to have different names that distinguish among the possible arrangements. Many compounds, particularly those that have been known for a relatively long time, have more than one name: a common name sometimes several , and a systematic name, which is the name assigned by adhering to specific rules. Like the names of most elements, the common names of chemical compounds generally have historical origins, although they often appear to be unrelated to the compounds of interest.

Your textbook has tables of the names and formulas of common cations and anions, and discusses the rules of nomenclature in detail. You will need to spend some time with this material, as the formal rules of nomenclature may not be presented in lecture, although they will certainly be used in discussions of Lewis structures and reaction chemistry.
