What were the three missing elements in mendeleyev chart?
The missing elements that Mendeleev predicted in his periodic table were germanium, gallium, and scandium. Mendeleev left gaps in the table for these elements based on the patterns he observed in the known elements at the time.
Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
What did the gaps on Mendeleev's tabel represent?
He predicted that elements with the predicted properties would be discovered to fill in these gaps.
Periodic table what was missing at first?
When the periodic table was first created by Dmitri Mendeleev in 1869, there were some gaps or missing elements that had not yet been discovered. Mendeleev left spaces in his table for these unknown elements, accurately predicting both their properties and where they would be located in the table once they were discovered. Over time, these missing elements, such as gallium and germanium, were discovered and filled in the gaps as Mendeleev had predicted.
What two elements did Dmitri Mendeleev switch?
Dmitri Mendeleev switched the positions of iodine and tellurium in his periodic table based on their properties, correctly predicting the existence and properties of missing elements.

Who arranged the elements by atomic mass and used it to predict properties of missing elements?
Independently by Dmitri Mendeleev and Lothar Meyer in 1869
Who predicted that the existence of several missing elements?
You think probable to Dimitri Mendeleev.
Who arrange the elements according to atomic mass and use the arrangement to predict the properties of missing elements?
Dmitri Mendeleev
What did the gaps on Mendeleev's tabel represent?
He predicted that elements with the predicted properties would be discovered to fill in these gaps.

Over time, these missing elements, such as gallium and germanium, were discovered and filled in the gaps as Mendeleev had predicted.
Mendeleev made the first periodic table around?
Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.
What two elements did Dmitri Mendeleev switch?
Dmitri Mendeleev switched the positions of iodine and tellurium in his periodic table based on their properties, correctly predicting the existence and properties of missing elements.
What did dimitri mendeleev recognize in 1869?
On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which described elements according to both weight and valence. _________________________________________________________________________ In1869, Mendeleev published the first periodic table. Within 16 years, chemists discovered the three missing elements scandium, gallium, and germanium. Their properties are close to those that Mendeleev had predicted.Over all he discovered the three new or missing elements.
What group of elements did Mendeleev omit?
i have no idea but i will check and keep you posted.
The atomic theory was supported by mendeleev when scientist did what?
The atomic theory was supported by Mendeleev when scientists discovered that elements displayed a periodic trend in their properties when arranged by increasing atomic weight. Mendeleev used this information to create the periodic table, organizing elements by their atomic weights and predicting the properties of missing elements.
Which property did Mendeleev primarily use to classify the element?
Mendeleev primarily used the element's atomic mass to classify them. He organized the elements into a periodic table based on their increasing atomic mass, allowing him to predict the properties of missing elements and arrange them in a logical order.
