摘要
确定氧化数的新方法是利用分子的Lewis结构和元素电负性表,画出键合电子的归属图,从自由原子的价电子数减去围绕分离原子的价电子数的差等于该原子的氧化数。
A new method for determination of Oxidation number is to use Lewis str-ucture for the molecule(or ion)and a table of electronegativity values, draw a return scheme of bonding electron, subtract the number of elec rons around each separate atom from the number of valence electrons the free atom would have, the difference is the exidation number.
