The elements in Group 1 are called ___. A. alkaline earth metals B. halogens C. noble gases D. alkali metals 相关知识点: 试题来源: 解析 D。解析:文中提到“the elements in Group 1, also known as the alkali metals”,即第一族的元素也被称为碱金属。
aUnlike halogens, the reactivities of alkali metals increase down the group; that is, elements in the higher numbered periods are more reactive than elements in the lower numbered periods. 不同于卤素,碱金属反应性增加在小组下; 即元素在更高的被编号的期间比元素易反应在更低的被编号的期间。 [...
The Halogens (Group 7) Fluorine, Chlorine, Bromine, Iodine, Astatine. Have 7 valence electrons (very reactive), they need 1 more to have a full valence! The Noble Gases (Group 8) Very stable and “unreactive” (inert). All have 8 valence e- except for Helium. Why is Helium still ...
