The standard variation of the periodic table. The periodic table of the chemical elements is a list of known Elements. In the table, the elements are placed in the order of their atomic numbers starting with the lowest number. The atomic number of an element is the same as the number of protons in that particular atom. In the periodic table the elements are arranged into periods and groups. A row of elements across the table is called a period. Each period has a number from 1 to 7. Period 1 has only 2 elements in it hydrogen and helium. Period 2 and Period 3 both have 8 elements. Other periods are longer. Elements in a period have consecutive atomic numbers. A column of elements down the table is called a group. There are 1. 8 groups in the standard periodic table. Each group has a number from 1 to 1. Elements in a group have electrons arranged in similar ways, which gives them similar chemical properties they behave in similar ways. For example, group 1. The periodic table can be used by chemists to observe patterns, and relationships between the elements. There are 3 main groups in in the Periodic Table metals, metalloids, and gases. For example, elements to the bottom and far left of the table are the most metallic, and elements on the top right are the least metallic. There are also many other patterns and relationships. There are two systems of group numbers one using Arabic numerals 1,2,3 and the other two using Roman numerals I, II, III. The Roman numeral names were used at first and are the traditional names the Arabic numeral names are newer names that the International Union of Pure and Applied Chemistry IUPAC decided to use as well.

Dmitry Ivanovich Mendeleyev 1. In his honour, element 1. Chemical Series of the Periodic Table. State at standard temperature and pressure. The color of the number atomic number above the element symbol shows the state of the element at normal conditions. Radioactivity. Those with dashed borders have only radioactive naturally occurring isotopesthose without borders are too radioactive to have been discovered yet.

Other widespread versions are shown below Theodor Benfey arranged the elements in a spiral, around hydrogen.

Dmitry Ivanovich Mendeleyev used a flower arrangement Actinides, Lanthanides are shown as loops beside the main group. Betterman arranged the elements by their isoelectric properties, which can be converted to a polynomial form. By WebElements the periodic table on the web.

The Chemistry Divisions Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element. Glossary. Group A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. An extended periodic table theorizes about elements beyond oganesson beyond period 7, or row 7. Currently seven periods in the periodic table of chemical elements.

You can use these file to print copies of the periodic table for yourself, groups of students, whatever. What you may not do is sell it, or distribute it on media which you sell. The 5 figure version is called webelementstable5sf2. This version is appropriate for most uses, in particular for school use and many university requirements. It lists the atomic weights to 5 significant figures, all that is needed for many purposes. The full version is called webelementstablefull2. This version is appropriate if you want the atomic weights to have the maximum number of figures. The estimated errors as given by IUPAC are also included. This will suit the professional in particular but is also suitable in many cases for school and university requirements. These files were updated 0. June 2. 01. 2 to include the latest IUPAC values.
