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...
Fluorine and brominehave properties similar to those of chlorine. What do fluorine chlorine and bromine have in common? As you can see in the periodic table below, thehalogensinclude the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). All of them are...
Concentrations of bromine, chlorine and iodine were determined in bulk rain as part of a detailed urban monitoring program. Instrumental neutron activation gives simultaneous nondestructive analysis of these halogens with detection limits of 2, 30 and 1 ng/g for bromine, chlorine, and iodine, respec...

Although it is the most stable chlorine oxide, Cl2O7 is strong oxidizer as well as an explosive that can be set off with flame or mechanical shock, or by contact with iodine. Nevertheless, it is less strongly oxidizing than the other chlorine oxides, and does not attack sulfur, phosphorus,...
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,...
5.2.7 Chlorine, Bromine and Iodine Chloryl fluoride, ClO2F, is the most common chlorine oxide fluoride and is commonly encountered in the reactions of the binary chlorine fluorides ClF, ClF3 and ClF5 with oxides and hydroxides. It is most conveniently prepared in high yield by the reaction of...
What is the electronegativity of iodine? What is the valence electron configuration for the chlorine atom? What is the most common isotope of bromine? What are halogens? What is unique about halogens? In what country was fluorine discovered?
