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.
Mendeleev's periodic table was 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 true or false?
True.
Why did mendeleev leave blank spaces on his periodic table?
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
How did mendeleev arrenge the elements of the perio dic table?
Mendeleev arranged the elements in order of increasing atomic weight because he saw that when arranged this way, certain patterns emergedin the properties of the elements.
Why did Dmitri leave blank on the preodic table?
There is no specific reason mentioned for why Dmitri Mendeleev left blank spaces on the periodic table. It is believed that he left these spaces to accommodate elements that were yet to be discovered or to demonstrate the existence of elements with certain properties that were predicted but not yet confirmed. These blank spaces eventually led to the discovery of new elements and validated Mendeleev's periodic table.
What determined the order of elements across a row in Mendeleev's periodic table?
Mendeleev organized the elements in his periodic table based on increasing atomic mass. He noticed that certain properties repeated periodically when the elements were arranged in this way.
What was the importance of mendeleev's periodic to chemists?
In Mendeleev's period table, the elements were arranged by both weight and valence. Mendeleev noticed certain elements were very close in weight and properties and hypothesized other elements that would lie between them. These were the basis of groups. He also noticed weights increased regularly and formed these into periods.

How Mendeleev organized his periodic table?
By the increasing Atomic Mass.
Who was the first time to organize the elements on the periodic table?
In 1869, a Russian chemist named Dmitri Mendeleev came up with a way of organizing the elements.and arranged them in ascending atomic number
Why couldn't Mendeleev organize the entire table during his research?
Mendeleev faced challenges in organizing the entire periodic table due to the limited number of known elements at the time and the lack of understanding of atomic structure. Some elements had not yet been discovered, and he had to leave gaps for these unknown elements, predicting their properties based on the patterns he observed. Additionally, discrepancies in atomic weights led to difficulties in placing certain elements accurately, prompting him to prioritize chemical properties over atomic mass in some cases.
Why was mendeleev's table accepted by other scientists?
Mendeleev's periodic table was accepted by other scientists because it successfully organized elements based on their atomic mass and revealed periodic trends in their properties. His predictions of undiscovered elements, such as germanium, gallium, and scandium, which matched their properties once found, further validated his framework. Additionally, Mendeleev's ability to correct certain atomic masses and leave gaps for yet-to-be-discovered elements demonstrated the table's robustness and utility in understanding elemental relationships. Overall, his systematic approach provided a powerful tool for chemists to predict and explain chemical behavior.
