A. different B. similar C. same D. opposite 相关知识点: 试题来源: 解析 B。“Elements in the same group have similar chemical properties.”可知同一组的元素有相似的化学性质。A 选项不同的、C 选项相同的、D 选项相反的均不符合语境。反馈 收藏 ...
chemical properties C. atomic radii D. ionization E. nergies 相关知识点: 试题来源: 解析 B。解析:文中提到“Elements in the same group have similar chemical properties. This is because they have the same number of valence electrons.”。
To answer the question "Elements in the same group have chemical properties. (similar/different)", we can follow these steps:Step 1: Understand the Concept of Groups in the Periodic Table - The periodic table is organized into
What do the alkali metals all have in common? a. They all have similar physical properties. b. They all undergo similar reactions. c. They all form +1 ions. d. They all have the same number of valence electrons. e. All of the above ...
Thus it is possible to arrange the list of elements in tabular form with elements having similar properties placed in vertical columns. Such an arrangement is called a periodic table. 早在 17 世纪末期,罗伯特•波义耳就开始了这项工作,他提出了现在公认的元素概念,大量的研究使 我们对元素极其化合物...
试题来源: 解析 D。解析:文章中明确提到“The elements in the same group have similar chemical properties. This is because they have the same number of valence electrons.”,即同一族的元素具有相似的化学性质是因为它们有相同数量的价电子。反馈 收藏 ...
