Chemistry is a fascinating subject, but with all the material to be covered in any chemistry course it can be overwhelming. There are several types of chemistryinorganic chemistry, biochemistry, and organic chemistry, for examplebut all have a similar foundation. Easy Chemistry Step-by-Step allows you to move at your own pace through basic chemistry concepts.

Some concepts will be easier than others to master. Each chapter begins with a foundation section that provides an introduction to the topic. This is followed by further, in-depth explanations. Step-by-step problem-solving strategies are provided to help build a solid foundation of chemical concepts. These strategies include questions to ask yourself while performing a skill and then examples for you to solve. Common mistakes are pointed out as missteps to be aware of.

The in-depth examples are followed by guided practice and exercises to try on your own. Although the chapters build on each other, they also stand alone so you can return to any particular concept and review it as needed. Learning chemistry is similar to learning a foreign language. You will learn the language of several types of compounds and their different naming systems. A solid foundation is important as you continue to take additional courses. Understanding the fundamentals of chemistry also requires knowledge of mathematics and how the mathematics relate to chemical concepts.

The goal of Easy Chemistry Step-by-Step is to provide the necessary foundation in chemical concepts and the mathematics of chemistry for you to be successful in your first chemistry course.

Elements and compounds have names. The names vary by language but the symbol and formula of the element or compound remain the same and are controlled by an international committee (IUPAC). Some examples include magnesio in Spanish, which is magnesium in English, yet both are the symbol Mg; argento in Italian, plata in Spanish, and silver in English all have the symbol Ag; and crypto in Italian and krypton in English both have the symbol Kr. To learn chemistry, you must first know the chemistry language of the elements! The periodic table shows the arrangement of the elements. Learning the symbols and their names will take practice.

For many elements, the name and symbol are easy to learn because the name and symbol are similar to each other. There is no reasoning to finding an element on the periodic table, such as going in alphabetical order. One way to help find an element is to know if the element is a metal or nonmetal. Metals are on the left of the table on the next page and nonmetals are on the far right.

Step 1. Is the element or symbol a metal? Remember to look on the left-hand side of the table. Problems It is important to know the names and symbols before trying to name compounds. Problems It is important to know the names and symbols before trying to name compounds.

Find the following elements on the periodic table and give their symbols. a. calcium b. zinc c. fluorine d. tin e. iron

a. Calcium is a metal, so look on the left-hand side. It is in the second column, the third one down, and has the symbol Ca. b. Zinc is a metal, so it is on the left-hand side. Looking, we find it toward the middle in the fourth row and it has the symbol Zn. c. Fluorine in a nonmetal and is found on the right-hand side in the next-to-last column.

It has the symbol F. d. Tin is a metal, so first look on the left-hand side. Looking, we find it toward the middle right in the fifth row;it has the symbol Sn.
