A method to calculate new valence electronegativity and the ionicity of chemical bond of the transition metal elements is also presented here.

提出了计算过渡元素价态共价半径公式;提出了计算过渡元素新价态电负和化学键离方法。

The essential feature of monomer molecules is the ability to form chemical Bonds (see Bonding) with at least two other monomer molecules (polyfunctionality).

单基本特是至少能与两个其它单形成化学键能力(多功能)。
