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.

EzraDmitri Mendeleev was able to determine the Atomic Mass and properties of each element, as well as predict the existence and properties of undiscovered elements based on the periodic patterns he observed in their properties. He arranged the elements in his Periodic Table in order of increasing atomic mass to demonstrate their recurring chemical and physical properties.

What types of atoms would you expect to find in the element sodium?
you only find 1 type of atom in an element
What evidence did Dmitri mendeleev find on the impact of the development of the periodic table?
Non
Where would you find mendeleev's periodic table?
Where do you find it? In every chemistry book out there. It's a very well organized chart that lists properties and characteristics of every element in the universe. Its arrangement also displays trends of different families of elements. The more you learn about it, the more it teaches you!
What does an element atomic number equal?
The atomic number of an element equals the number of protons in the nucleus of an atom of that element. It determines the element's identity on the periodic table and is unique to each element.
How do you find an element's relative?
how do you find an element's group
