Characteristic in the Periodic Table of Elements at Present

介绍了化学元素周期表的两个特点:(1)元素已达118号,远远超出当前国内大中专化学教材所列的112号元素数;(2)第六周期和第七周期ⅢB元素是Lu和Lr,而不是La和Ac.

This paper introduces two characteristics in the periodic table of elements at present.They are:1.The elements has been synthesized to 118, far more than 112 listed in domestic college chemistry books.2.ⅢB elements of sixth and seventh periodic are Lu and Lr,not La and Ac.
