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.
What else can I help you with?
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 number of protrons of whichever element you choose. Each element has an exact number of protrons.
How do you find an element's relative?
how do you find an element's group
What is each number that you find in a matrix?
Each number in a matrix is called an element.
What are characteristics of atomic number?
The atomic number of an element tells you how many protons there are in each nucleus of each atom of the element. On the periodic table, you find the atomic number at the top of the box for each element.
What are the characteristics of atomic number?
The atomic number of an element tells you how many protons there are in each nucleus of each atom of the element. On the periodic table, you find the atomic number at the top of the box for each element.
What did mendeleev use to find the elements with?

How can one determine the empirical formula from mass data?
To determine the empirical formula from mass data, you need to find the molar mass of each element in the compound. Then, divide the given mass of each element by its molar mass to find the moles of each element. Finally, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio of elements, which represents the empirical formula.
How do you find hown many shells are in anatom?
refer to a periodic able and find out which element your are looking for and see what period is it in (horizontally)
What is mendelevium?
256Md has been used to find out some of the chemical properties of the element Mendelevium, while in an aqueous solution. There are no other uses of mendelevium and only trace amounts of the element have ever been produced.
What did dimetri mendeleev find out about the periodic table?
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today.
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
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
You would need to know the abundance of each isotope to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and then summing these values together.
