When these elements were finally discovered with properties almost identical to his predictions, the scientific community universally accepted his periodic system.
How the differs from Mendeleev's original version The biography of Mendeleev himself Periodic Table of Elements - American Chemical Society
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
Other scientists forced elements into rigid grids even when the properties did not match.
He assumed the empty spaces belonged to elements that humans had simply not discovered yet. 🔮 The Famous Predictions When these elements were finally discovered with properties
If you'd like to explore this further,what was actually found
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 He assumed the empty spaces belonged to elements
If the next heaviest element did not fit the chemical properties of the column, Mendeleev skipped a box and moved it to the column where it did fit.
