When these elements were finally discovered with properties almost identical to his predictions, the scientific community universally accepted his periodic system.

He assumed the empty spaces belonged to elements that humans had simply not discovered yet. 🔮 The Famous Predictions gthbjlbxtcrfz nf

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 When these elements were finally discovered with properties

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

Other scientists forced elements into rigid grids even when the properties did not match.
