在化学元素的瑰宝中，卤素(Halogen)家族独树一帜，由五位成员组成：活泼的氟( Fluorine )、活泼的氯( Chlorine )、神秘的溴( Bromine )、珍贵的碘( Iodine )，以及极其罕见的砹(Astatine)。这些元素位于第七主族，以其独特的化学性质，轻松与其它元素形成化合物，创造出无数神奇的化学反应。卤素化合...
The four elements, fluorine (F), chlorine (Cl), bromine (Br) and iodine (I), constitute a well-marked group in the Periodic Classification (see p. 26), and show a number of similarities and progressive variations in their properties. All unite readily with the metals to form salts such...

性质:周期表中ⅦA族元素,包括氟、氯、溴、碘、砹,其中砹是人工放射性元素。由于它们都能直接与金属化合形成盐类,并在自然界都以典型盐类形式存在,故得名。含义是成盐元素。卤素原子最外电子层都有7个电子,价电子层结构为ns2np5,容易接受1个电子而很难失去电子;都是活泼非金属,非金属性比同周期的氧族元素强,...
