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 ...
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
Each vertical column in the periodic table is called a group. The elements in the same group have similar chemical properties. Groups are given names based on the properties of the elements. For example: Group 1 elements are called al...
Why do elements in the same group of the periodic table have similar properties? What does each different element on the periodic table of elements represent? What do the elements in each column of the periodic table have in common?
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。
The Zaprionus genus shares evolutionary features with the melanogaster subgroup, such as space and time of origin. Although little information about the transposable element content in the Zaprionus genus had been accumulated, some of their elements appe
It is over taken by all the elements above it and is not overly reactive with water. Chemical trends in group 7 Bromine is the third element within group 7, It is also the third most reactive in the group. Bromine displaces the elements below it: Iodine and astatine on account of them...
How do electron configuration within the same group of elements compare? The ground-state electron configuration of an atom is 1s^22s^22p^63s^23p^4. What is the valence-shell configuration of the atom in the same group, but in Period 5?
