Periodic table (wide) This is a version of the periodic table of the elements that places all elements in the same rows. For more information on its contents
Inner Transition Elements: They are shown in green in Figure 1. The valence shells of the inner transition elements consist of the (n –2)f, the (n –1)d, and the ns subshells. Inner transition elements constitute f-block as the last electron enters an f orbital. The principal quantum...
periods are designated as main group elements, and the members of the other groups are called transition or inner transition elements. (在元素周期表中) ,水平的每一排元素组成了一个周期。应当注意的是,周期的长短是有变化的。首 先是一个含有 2 种元素的极短周期,接着是两个短周期,每一周期含有 8...
This periodic table of elements provides comprehensive data on the chemical elements including scores of properties, element names in many languages and most known nuclides (Isotopes). Below the table there is a "Periodic Table Sorted By" section with links that will sort chemical elements by vario...

Of these elements, only thorium (Th) and uranium (U) occur naturally on Earth in substantial amounts. All are radioactive. The actinides and the lanthanides together form a group called the inner transition metals. Transition metals: Returning to the main body of the table, the remainder of...
There are some exceptions to this rule in the transition elements, which fill the shorter columns at the center of the periodic table. These transition elements have partially filled d-orbitals, which contribute to their unique properties. This distinguishes them from the main group elements that ...
Groups 3-12: The Transition Metals Inner Transition Elements- The inner transition metals are the two rows of elements that appear below the main body of the periodic table. Lanthanides - shiny, metallic elements with atomic numbers 57 through 71. Actinides - metallic elements with atomic numbers...
