化合价主要是指某一化学元素的一个原子与其他元素的原子构成的化学键的数量。原子核与其外围的电子是原子的主要组成部分,在后者围绕前者进行分层运动的情况下,不同原子之间的连接会让原子的数量产生一定的变化,在变化过程中,电子数的偏移数量就可以被看作是化合价。在化学领域,“化合价”与氧化还原 The valence is mainly the number of chemical bonds between one atom of a certain chemical element and the atoms of other elements. The nucleus and its peripheral electrons are the main components of the atom. When the latter is stratified by the former, the connection between different atoms will change the number of atoms. In the process of change, the number of electrons The amount of shift can be seen as the valence. In chemistry, “valence ” and redox
