which element finally fit into the blank space of Mendeleev's periodic table which was originally left blank for the Predicted Eka - aluminium element ?
Answers
Answer:
Gallium is Eka aluminium in periodic table.
Answer:
Gallium is that element which fits into the blank space of Mendeleev's periodic table which was originally left blank for the Predicted Eka - aluminium element.
Explanation:
Mendeleev's Periodic Table=>
1. Dmitri Ivanovich Mendeleev gave a periodic table having chemical elements in 1869.
2. It was based on the properties that the elements were placed in periodic table from lightest to heaviest.
3. He also left some blank spaces in the table to which he predicted that there will be elements which will be discovered in future and he also gave properties too for them.
4. There were three unknown elements predicted by him along with the properties and he named them eka-boron, eka-aluminium and eka-silicon and also gave atomic mass 44, 68, and 72 respectively.
5. There was another predicted element which was named eka-manganese.
6. In future , these were named Scandium for eka-boron, Gallium for eka-aluminium, Germanium for eka-silicon and Technetium for eka-manganese and these were lighter than the earth-rare elements.
