What was Mendeleev able to find out for each element?
He was able to work out the atomic mass of the missing elements, and so predict their properties. And when they were discovered, Mendeleev turned out to be right. For example, he predicted the properties of an undiscovered element that should fit below aluminium in his table. When this element, called gallium, was discovered in 1875, its properties were found to be close to Mendeleev's predictions. Two other predicted elements were later discovered, lending further credit to Mendeleev's table.
How did Mendeleev place germanium on the periodic table?
Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.
How did mendeleev explain blank spaces left in his periodic table?
On his Periodic Table Mendeleev left the blank spaces, because he thought there would be elements that would follow his pattern.
When Mendeleev published his periodic table there were some spaces for undiscovered elements Figure 15-1 is a section of a similar table A reasonable value for the atomic mass of the missing element?
