More so than any of the other major groups of elements in the periodic table, the transition metals have shaped human history and have been the workhorses of industry. The discovery of metallic copper ended the Stone Age and ushered...
Transition metals are in the d-block and have valence electrons in the d-orbital's. They can form multiple oxidation states and form different ions. Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and have valence electrons in the f-orbital's. They con...
化学里的元素(element)基本可以分成 metal(金属) 与 nonmetal (非金属) 两类,金属元素又有一系列特别的 transition metals(过渡金属)。周期表上金属与非金属交界处又有着一系列具有特殊性质的元素,被称为 metalloid(准金属) 或 semimetal(半金属X。 以下是几种常见元素信息名称的中英对照: ...
In this article, we'll break down everything you need to know about the periodic table. From its history and layout to its key elements and groups
Transition metals The yellow block of elements in the centre of the table is known as transition metals. These elements are very useful as they conduct electricity and are mostly solid at room temperature. Halogens – Group 7 Halogens are the elements in light purple. The halogen column is ...
