Dmitry Mendeleev

The largest chemist who discovered the periodic law of the elements
Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).More Dmitry Mendeleev quotes [07/28/2011 05:07:30]
The establishment of a law, moreover, does not take place when the first thought of it takes form, or even when its significance is recognised, but only when it has been confirmed by the results of the experiment.More Dmitry Mendeleev quotes [07/28/2011 05:07:39]
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.More Dmitry Mendeleev quotes [07/28/2011 05:07:32]
Certain characteristic properties of elements can be foretold from their atomic weights.More Dmitry Mendeleev quotes [07/28/2011 05:07:23]
No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.More Dmitry Mendeleev quotes [07/28/2011 05:07:00]
