元素及其化合物是‘元素化学’的主要研究对象,在分子、原子和电子运动规律的水平上研究元素及其无机物的:‘结构与性质、性质与反应、反应与应用,以及新型无机物的合成与性能’的元素化学谓之‘元素无机化学’。元素是这个领域的‘主角’,其存在(丰度与形态)、‘品格’(原子序Z—原子核类型)、‘特长’(可变的价层电子结构导致的理化特 Elemental and its compounds are the main research objects of ’elemental chemistry’. They study the structure and properties, properties and reactions, reactions and applications of new elements and their inorganics at the level of molecular, atomic and electron movement patterns. The synthesis and performance of the elemental chemistry that elemental inorganic chemistry. Elements are the ’protagonists’ in this field, their existence (abundance and morphology), ’character’ (atomic Z-nuclear type), ’specialization’ (physical and chemical specialization caused by a variable valence electron structure
