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...
