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
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。
This serves as a complement to numerically and approximately solving the many-electron Schrdinger equation to understand the behaviour of chemical elements. Besides the general theory, specific results are compared with experimentally measured chemical properties.Abram I. Fet...

The present form of periodic table is helpful to the students of chemistry in a way that they can corelate or compare the different properties of different elements from this table and they can actually study the elements properly from this table....
(1) One of the major classes or divisions into which elements are arranged in the periodic table (vertical columns). The classification is made according to the properties of the elements, those whose properties are similar occupying one group. Groups I through VII are divided into subgroups (...
