- 5(A)Quiz - History of the Periodic Table Why did Mendeleev leave spaces blank when he was designing his periodic table? He knew that no element would ever have the properties to fit in the blank spaces. Only inert gases could fit in the blank spaces and they hadn't been discovered yet. He left spaces blank at random and found a way to make newly discovered elements fit in. He knew that there were elements yet to be discovered and that they would have properties that would fit perfectly in the blank spaces. POSSIBLE POIN
