摘　　要：利用原子的价层轨道能、共价半径和有效主量子数为主要参数,以静电力为基础计算了稀有气体的价态元素电负性,从而使对价态元素电负性的计算扩展到了86种元素,由此,产生了一套价态元素电负性的新标度,该标度不但容易理解和计算,而且标度值比已有的文献值更接近传统的鲍林电负性值。The electronegativities of the Noble Gas elements in valence states are calculated on the basis of electrostatic force by using observed energy of valence orbits of atom, at the moment the covalent radius and the effective principal quantum number are applied as main parameters. This leads to a new set of the electronegativities of the elements in valence states for 86 elements in the periodic table they can be easily calculated and understood. And such values are in substantially better agreement with traditional Pauling values than those of electronegativities of elements published in literatures.
