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. The range in these properties is considerable; therefore the statements are comparative with the general properties of all the other elements.

To write a complete electron configuration for an uncharged atom,. Determine the number of electrons in the atom from its atomic number. See Below. Add two electrons to each s sublevel, 6 to each p sublevel, 10 to each d sublevel, and 14 to each f sublevel. There are three ways to predict the order of filling of the orbitals. Probably the least reliable method is to memorize the following list even though it shows the order of filling of all the orbitals necessary for describing the ground state electron configurations of all of the known elements. Instead of relying on memorization, you can use the memory aid shown below to remind you of the correct order of filling of the sublevels.

Are you still here? Well, I guess I should tell you something about the periodic table — like how to read it. This last convention arose during the Transfermium Wars of the late Twentieth Century, which, despite sounding like a science fiction battle for supremacy of the galaxy, was actually nothing more than an academic argument. At this time, nuclear chemists in the United States and the Soviet Union were synthesizing elements heavier than fermium thus the adjective "transfermium" and the governments of the United States and the Soviet Union were embroiled in the Cold War thus the noun "wars". Put the two together and you get Transfermium Wars — a bunch of chemists arguing about whose laboratory and by proxy, whose superpower nation was the best. Naming rights go to the lab with priority in a discovery. The International Union of Pure and Applied Chemistry IUPAC , which establishes rules for things like naming chemical elements, invented systematic names to impose a kind of armistice on warring chemists.

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. Perhaps the most 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. From Wikipedia, the free encyclopedia. A list of the identified chemical elements.
