Mendeleev used the elements above his empty gaps to calculate and predict the exact physical and chemical properties of the missing elements: →right arrow Discovered 4 years later as Gallium "Eka-boron" →right arrow Discovered 10 years later as Scandium "Eka-silicon" →right arrow Discovered 17 years later as Germanium
The single most defining feature of Dmitri Mendeleev's original periodic table was his decision to and use them to predict undiscovered elements . 🚀 How the Feature Worked gthbjlbxtcrfz nf
He assumed the empty spaces belonged to elements that humans had simply not discovered yet. 🔮 The Famous Predictions Mendeleev used the elements above his empty gaps
