1、s区和p区元素化学引言Introduction of the Chemistry of s and p Elements周期系中的主族元素(the elements in the main subgroups)即为s区和p区元素。每一周期(period)以两种s区元素开始,后面是六种p区元素(第一周期例外,只有两种元素)。一、原子半径(Atomic Radii)、电离势(Ionization Energy)、电子亲和...
This is one of the most important relationships in chemistry; atoms in the same group have similar chemical properties because they have the same number of valence electrons. 这是化学中的最重要的关系之一;位于同一组的原子具有相似的化学性质,因为它们的价电子数相同。 Each group 1 element has a val...
organic chemistry, reviewThis chapter discusses the element displacement principle of p-block element chemistry. It explores that the elements situated up to four places before a noble gas change their properties by taking up 1, 2, 3, or 4 (x) hydrogen atoms so that the resulting radicals ...
