<h2>Dmitri Mendeleev</h2> | |
<h3><u> Information About Dmitri Mendeleev:</u></h3> | |
<p>Dmitri Mendeleev was a Russian chemist who formulated the periodic law and created the first widely recognized periodic table of elements in 1869.His genius lay in arranging elements by atomic mass and predicting properties for elements that hadn't been discovered yet, leaving gaps in his table for them. The later discovery of elements like gallium and germanium, which matched his predictions for eka-aluminum and eka-silicon respectively, confirmed the accuracy of his work.</p> | |
