The periodic table of the elements was developed well over 100years ago. At that time it was an empirically derived arrangement based on the physical properties of the known elements. The modern periodic table is an arrangement of eleme...

One of the early models of the periodic table arranged elements by atomic weight, which naturally grouped elements with similar properties together. 有种早期的元素周期表按原子量来排列元素,自然就将性质相似的元素放在一起了。 However, certain elements were outliers, and did not fit in their groups....
There were certain irregularities in Mendeleev's table due to thefact that he ordered the elements by atomic mass (ex: tellurium, iodine) E. Modern Periodic Table1. Modern Periodic Law: similar properties of the elements occurperiodically when arranged by their atomic (not masses)2. The ...
