基础化学教学中希有气体原子半径的处理

Discussion on the Atomic Radii of the Noble Gases in Basic Chemistry Teaching

基础化学教材中希有气体原子半径的表列数据及其递变规律的表述等方面处理不当。建议采用有实测依据的希有气体原子新共价半径值,以利原子半径概念及其递变规律的教与学。

The atomic radii of the noble gasesis misconducted in the basic chemistry textbooks. It is suggested that the new value of covalent radii of the noble gases should be used so as to fit the teaching and learning of concept of atomic radii and its shifting rules.
