The modern periodic metal was formed by a scientist named Dmitri Mendeleev. He arranged the elements on the periodic table by increasing atomic weight. The elements found in the same column are in the same group, while the elements found in the same row are in the same period. The elements...

网络释义 transition-metal n. 1. 过渡金属(位于元素周期表中心的一组金属元素,可形成有色化合物,常作为催化剂)one of the group of metals in the centre of the periodic table(= a list of all the chemical elements) which form coloured compounds and often act as catalysts(= substances that make ...
The elements of the periodic table can be grouped into alkali metals, alkaline earth metals, lanthanides, actinides, transition metals, post-transition metals, metalloids, reactive nonmetals, and noble gases. Transition metal or transition elements are a set of elements located in groups 3 to 12...
However, metal elements generally lose electrons more easily than other elements, so metals are known for oxidation. For example, a rusty bike. Each element has unique oxidation states, with the most common state bolded in the periodic table. Elements can also have multiple possible oxidation ...
