Alkali Metals: Group 1 elements; highly reactive with one outer electron. Alkaline Earth Metals: Group 2 elements; less reactive with two outer electrons. Transition Metals: Central block elements, multiple oxidation states, good conductors...
Group 1: Alkali Metals The alkali metals are located in Group IA (first column) of the periodic table. Sodium and potassium are examples of these elements. Alkali metals form salts andmany other compounds. These elements are less dense than other metals, form ions with a +1 charge, and ha...
Group 1 (also known as the alkali metals) is the column on the far left of the table. Elements in the same group have similar, but not identical characteristics. This is because they all have the same number of electrons in their outermost shell. You can tell a lot about an element ...

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: ...
For example, the alkaline metals lie in one group (group 1) and share similar properties, such as high reactivity and the tendency to lose one electron to arrive at a noble-gas electronic configuration. Modern quantum mechanics explains these periodic trends in properties in terms of electron ...
