Who is the chemist responsible for the periadic table?
Dmitri Mendeleev is credited with the development of the periodic table in 1869. Mendeleev organized the elements based on their atomic mass and properties, creating a system that allowed for predicting the properties of undiscovered elements. His work laid the foundation for the modern periodic table.
How did Mendeleev arragnge the known elements in his periodic table?
Mendeleev arranged the known elements in his periodic table by increasing atomic mass and organizing them in a way that elements with similar properties fell into the same columns (groups). Gaps were left for undiscovered elements, which Mendeleev predicted would be found in the future.
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.
Who was the first person to publish a periodic table?
Dmitri Mendeleev is credited with publishing the first widely recognized periodic table of elements in 1869. He organized the elements based on their atomic mass and predicted the properties of missing elements, allowing for future discoveries.
Why was Mendeleev's decision to leave blank spaces on his table sometime referred to as his most significant contribution to periodic table?
Mendeleev thought about the future and realized that it was entirely unlikely that all earthly elements had been discovered, so he left blank spaces in his table and even predicted some of the elements that would fit in those spaces. Surprisingly enough, as time passed, chemists began discovering many of the elements that he had predicted, which fit perfectly into his periodic table.
Who created the first acceptable periodic table?
Dmitri Mendeleev is credited with creating the first widely accepted periodic table of elements in 1869. He arranged the elements according to their atomic mass and properties, predicting the properties of missing elements and leaving gaps for future discoveries.

What is a sentence for foresee?
i could foresee the future
What is a elementary sentence for foresee?
She can foresee the future. I didn't foresee that happening!
How did Mendeleev arragnge the known elements in his periodic table?

Did Mendeleev leave gaps in the table for undiscovered elements?
Yes, Mendeleev left gaps in his periodic table for undiscovered elements. He predicted the properties of these missing elements based on the trends in the known elements and their positions in the table. This helped in the discovery of elements such as gallium, scandium, and germanium.
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.
Why did mendeleev leave gaps in the table?
Scientists suggest Mendeleev left gaps in the periodic table because Mendeleev knew the elements existed; however, was unable to prove it.
How did mendeleev organize the periodic table?
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
How do you spell sier?
Seer, meaning one who can foresee the future.
When am i getting married?
Sorry, we don't have the ability to foresee the future.
Why did Mendeleev leave spaces in his table?
Because he knew from his already discovered periods and groups of elements that the gaps would be filled by newly discovered elements. If you have a gap such as this, 3d5__3d7 along a period's outer valance level you can predict, which Mendeleev did, that the element with the outer valance number, 3d6, will be found in the future.
