How do the properties of eka-aluminium element predicted by Mendeleev compare with the actual properties of gallium element?
The properties of eka-alumiunium, predicted by Mendeleev, which was undiscovered then, were almost similar to the actual properties of the element discovered later on. The comparison table below shows the similarities in the properties of the undiscovered element then and the actual element (Gallium).
|Melting point||low||30.2oC (low)|
|Formula of oxide||Ea2O3||Ga2O3|
|Formula of chloride||EaCl3||GaCl3|
