Dmitri Mendeleev published the first periodic table in 1869,in which the elements were ordered according to atomic weight.Based on the work of physicist Henry Moseley,the periodic table was reorganized on the basis of increasing atomic number rathe than on atomic weight.The revised table could be used to predict the properties of elements that had yet to be discovered.Many of these predictions were later substantiated through experimentation.This led to the formulation of the periodic law,which states that the chemical properties of the elements are dependent on their atomic numbers.
Elements in the periodic table are arranged in periods(rows)and groups(columns).Each of the seven periods is filled sequentially by atomic number.Groups include elements having the same electron configuration in their outer shell,which results in group elements sharing similar chemical properties.The electrons in the outer shell are termed valence electrons.Val
元素周期表 介绍
Dmitri Mendeleev published the first periodic table in 1869,in which the elements were ordered according to atomic weight.1869年门得列夫首次出版了元素周期表，在元素周期表中他将元素依原子量（原子质量）大小排列。Based on the work of physicist Henry Moseley,the periodic table was reorganized on the basis of increasing atomic number rathe than on atomic weight.根据物理学家亨利·莫斯莱的研究，周期表被认为是基于原子序数而不是原子的质量排列的。The revised table could be used to predict the properties of elements that had yet to be discovered.被修改的表格可以用于推测还未发现的元素的性质。Many of these predictions were later substantiated through experimentation.这些推测中很多部分都被后来的实验证实了。This led to the formulation of the periodic law,which states that the chemical properties of the elements are dependent on their atomic numbers. 这导致了元素周期律的形成，元素周期律阐述了元素的化学性质是随原子序数逐渐变化的。
Elements in the periodic table are arranged in periods(rows)and groups(columns).元素在周期表中按照周期（横行）和族（竖列）排布。Each of the seven periods is filled sequentially by atomic number.7个周期中每个周期都是按原子序数的顺序填入的。Groups in
