The highlighted elements are considered the metal elements. Most elements can be considered metals. They are grouped together in the middle to the left-hand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals , lanthanides, and actinides.

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. Many of the elements are technologically important: titanium , iron , nickel , and copper , for example, are used structurally and in electrical technology. Second, the transition metals form many useful alloys , with one another and with other metallic elements.

Джабба посмотрел на экран и в отчаянии всплеснул руками. Новый порядок букв показался не более вразумительным, чем оригинал.
