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. For example, the systematic name for KNO 3 is potassium nitrate, but its common name is saltpeter. In this text, a systematic nomenclature is used to assign meaningful names to the millions of known substances.
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.
Ionic compound is represented by a formula unit, the lowest ratio of atoms in the compound. Page Naming Ionic Compounds. (positive metal ion +.
3.6: Names and Formulas of Inorganic Compounds
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.

Chemistry pivots on and around the Chemical Formulas. From representing an atom to presenting information about chemical proportions of atoms, chemistry formula plays a substantial role in understanding various concepts of chemistry. To score well in chemistry, students must learn certain Important Chemistry Formulas. Therefore, our team of chemistry examination experts has tried to consolidate all the important chemistry formulas at one place including Chemistry formula charts, chemical names, and formulas, organic chemistry formula, important equations etc. Chemical Formulas in Chemistry is fundamentally a type of shorthand required to represent the elemental state of in a compound. The Periodic Table is full of various types of elements along with the short symbols.
Here are printable chemistry worksheets in pdf format. The second worksheet asks for the chemical name based on the chemical formula. Answer keys are provided separately. Formula Worksheet Set 1. Formula Worksheet Set 2. In order to complete these worksheets, you may wish to review the rules for naming ionic compounds and covalent compounds.
Approximately one-third of the compounds produced industrially are organic compounds. All living organisms are composed of organic compounds, as are most foods, medicines, clothing fibers, and plastics. The detection of organic compounds is useful in many fields. By analyzing these organic gases and isolating the individual components, preservationists are better able to determine the condition of an object and those books and documents most in need of immediate protection. The simplest class of organic compounds is the hydrocarbons, which consist entirely of carbon and hydrogen. Petroleum and natural gas are complex, naturally occurring mixtures of many different hydrocarbons that furnish raw materials for the chemical industry.

But you may not have that much amount of time in your hands!! Last minute revision involves checking out all the formulae, diagrams of organic molecules etc. And jotting them down all at one place would require the same amount of time as it did when reading about them at first place. The given chapter-wise chemistry formulae sheets are in.
Chemical Formulas Assignment. A form of sugar called glucose has the chemical formula C6H12O6. From this formula, state the name of the elements and the number of atoms needed to make one molecule of glucose. State the identity and the number of atoms of each element in the given number of molecules in the table below.
Below are some example elements and compounds and their chemical properties. Also known as water, this particular compound is made up of two elements — oxygen and hydrogen. While both oxygen and hydrogen are more common in gaseous form, water is a fluid form.
