This is a list of the chemical elements which have been identified as of A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei i. A popular visualization of all elements is the periodic table of the elements , a convenient tabular arrangement of the elements by their chemical properties that uses abbreviated chemical symbols in place of full element names, but the simpler list format presented here may also be useful. Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight , density , and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.

The Chemical Elements and their Symbols

This is a list of chemical elements , sorted by atomic mass or most stable isotope and color coded according to type of element. Each element's atomic number , name, element symbol , and group and period numbers on the periodic table are given. The number in parenthesis gives the uncertainty in the "concise notation" dis given in parenthesis next to the least significant digits to which it applies", e. For artificial elements the nucleon count of the most stable isotope is listed brackets.

However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.

Note 2 : The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table. Note 3 : The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.

Note 4 : The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. Note 5 : The atomic weight of commercial Lithium can vary between 6.

For chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass weight. Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor s , non-metal s , inert noble gas ses , Halogens, Lanthanoides, Actinoids rare earth elements and transition metals. Click here: for a schematic overview of the periodic table of elements in chart form. Do you need to know the weight of some molecules?

Sometimes it's nice to have a paper version of the periodic table of the elements that you can refer to when working problems or doing experiments in the lab. This is a collection of periodic tables that you can print and use. Note: For values featuring all elements, more free printable periodic tables are also available. Here is the pdf file of the color periodic table so you can save and print it.

Transition metal , any of various chemical elements that have valence electrons—i. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated. They occupy the middle portions of the long periods of the periodic table of elements between the groups on the left-hand side and the groups on the right. The most striking similarities shared by the 24 elements in question are that they are all metals and that most of them are hard, strong, and lustrous, have high melting and boiling points, and are good conductors of heat and electricity.

Periodic Table Fun Activities. Reading Strategy page Previewing Before you read, complete the table by writing two questions about the periodic table on pages — There are endless facts to memorise, and there are few obvious and intuitively pleasing answers to questions such as why the periodic table has eight columns and not seven or nine.

Here is a list of elements of the periodic table , their atomic numbers, and element symbols. The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Each element has a symbol, which is a one- or two-letter abbreviation of its name. Sometimes the symbol represents an old name e. The PDF file is optimized for printing. Right now, there are no blank spaces in the periodic table up to element
