![]() Other tables include two numbers, which represent a range of values. Sometimes a periodic table cites a single value for atomic weight. ![]() The element's atomic mass in atomic mass units is a weighted average mass of the element's isotopes. ![]() Changing number of electrons produces ions while changing the number of neutrons produces isotopes. Variation in the number of electrons or neutrons does not change the type of element. The number of protons is the deciding factor when distinguishing one element from another. The atomic number is how many protons an atom of that element contains. The modern periodic table is organized in order of increasing atomic number. Usually, the symbol is an abbreviation of the element name, but some symbols refer to older names of the elements (for example, the symbol for silver is Ag, which refers to its old name, argentum). Each symbol is either one or two letters in length. In some cases, the abbreviation comes from the element's Latin name. Each element's cell typically contains lots of important information about that element.Įlement symbols are abbreviations of the element's name. Package content is not flexible and cannot be modified.The periodic table contains informative cells for each element arranged by increasing atomic number and chemical properties. Please note that if your order ships in multiple boxes, package components may not all be in the same box. The package item number is also listed at the bottom of your packing slip for reference. On your packing slip, package components are picked and packed individually and are identified with the code "PKGCMP" in the price column. ![]() Any backordered components will ship separately as they become available. In-stock components will ship according to our normal shipping time. When you order a package, you are charged one price for all package items. Because most package items or components are also sold separately and may be components of multiple packages, these items may not have the same inventory availability at any point in time. Although packages are sets, items are not physically bundled together. Any item sold as a package on our website is identified by a unique alpha-numeric item number (such as "APH1AB"). A listing of individual items that make up a package is provided on the package item's product detail page along with real-time item availability of those items. This is a fun reference that reminds us that chemistry doesn't have to be boring and dull it can also be full of personality! ~ Donna Publisher Description:Ī "package" is made up of two or more items sold as a set, often for a reduced price. A summary, written in first person, tells the reader a little more about the element.Ī poster of the Periodic Table is included in the back of the book (perforated for easy removal), and includes the whimsical, animated character for each. Each element is represented by a little animated character (much like Anime) and accompanied by that element's data symbol, atomic number, atomic weight, color, standard state, density, melting point, boiling point, date of discovery or earliest known use and classification. Now 192 pages the chapters include Alkali Metals, Alkaline Earth Metals, Transition Elements, Boron Elements, Carbon Elements, Nitrogen Elements, Oxygen Elements, Halogen Elements, Noble Gases, Lanthanoid Elements, Actinoid Elements and the Superheavies (elements 104-112). Updated and expanded this new edition introduces your students to even more characters of the Periodic Table (all 118 of them!).
