What else can I help you with?
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
Main idea of mendeleevs first periodic table?
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
Why are the hydrides of mendeleevs group 1 and 7 placed in separate groups?
Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and physical properties of the elements next to a gap, he could also predict the properties of these undiscovered elements. For example, Mendeleev predicted the existence of 'eka-silicon', which would fit into a gap next to silicon. The element germanium was discovered later. Its properties were found to be similar to the predicted ones and confirmed Mendeleev's periodic table.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
Why the improvement in Mendeleevs periodic table was made?
To understand the concept of Periodic Table
What effect did the discovery of the gallium have on the acceptance of Mendeleev's table?
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.
How was Dmitri Mendeleev able to predict the properties of germanium?
Dmitri Mendeleev was able to predict the properties of germanium by leaving gaps in his periodic table for elements that were yet to be discovered. He noticed a pattern in the properties of known elements and used this pattern to predict the existence and properties of undiscovered elements, such as germanium.
How could you use Mendeleevs periodic table to identitify new elements?
Mendeleev's periodic table can be used to predict the properties of unknown elements based on their position in the table in relation to known elements. Gaps in the periodic table can suggest the possibility of unknown elements with specific properties, guiding scientists in their search for new elements that fit those predicted properties. By applying Mendeleev's periodic law, researchers can make educated guesses about the characteristics of undiscovered elements and tailor their experimental efforts accordingly.
In Mendeleevs periodic table elements in each column had similar?
Chemical properties as they possessed the same number of valence electrons, leading to similar reactivity and bonding behavior. This organization allowed Mendeleev to identify patterns and predict the properties of undiscovered elements.
