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
All the members of the alkali metal family form ions having a charge of 1+ only. In contrast, the elements of group IB-copper, silver, and gold-are comparatively inert. They are similar to the alkali metals in that they exist as 1+ ions in many of their compounds. However, as is ...
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 ...
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 ...
Elements in the same group often have similar chemical properties ___ they have the same number of valence electrons. A. because B. so C. but D. or 相关知识点: 试题来源: 解析 A。因为同一组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,所以用 because。
