The following names for specific groups in the periodic table are in common use: Group 1: alkali metals Group 2: alkaline earth metals Group 11: coinage metals (not an IUPAC approved name) Group 15: pnictogens (not an IUPAC approved name) ...
Group 1 (with one valence electron) and Group 2 (with two valence electrons) are called thealkali metalsand thealkaline-earth metals, respectively. Two series of elements branch off from Group 3, which contains thetransition elements, or transition metals; elements 57 to 71 are called thelantha...

periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals;...
Alkali metals form a part of the leftmost group, i.e. group 1 of the modern periodic table. It contains six elements, which are collaboratively called the Lithium family. These metals are highly reactive metals of the periodic table due to the presence of one electron in their outermost shel...
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: ...
