Who arranged the periodic table according to increase in atomic weights?
Dmitri Mendeleev, a Russian scientist. He arranged cards in atomic weight order and noticed patterns (periods). This resulted in him being able to guess which elements were missing and complete the periodic table.
What did Dmitri mendeleev have to do to unlock the hidden pattern of the elements?
Dmitri Mendeleev unlocked the hidden pattern of the elements by arranging them in a table based on their atomic mass and chemical properties. He noticed that elements with similar properties occurred at regular intervals, leading to the creation of the periodic table. Mendeleev also left gaps for undiscovered elements and accurately predicted their properties based on the patterns he observed. This groundbreaking work laid the foundation for modern chemistry and our understanding of the elements.
What was the importance of Mendeleevs periodic table 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.
What describes why Mendeleev succeeded where others failed?
Mendeleev realized that some elements had not been discovered.
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 did Dmitri Mendeleev's periodic table look like?
Mendeleev noticed that patterns appeared when the elements were arranged in order of increasing atomic mass.
What did Mendeleev do that was important to chemistry?
Dmitri Mendeleev is known for creating the periodic table of elements. He arranged elements by increasing atomic mass and noticed patterns in their properties. His work laid the foundation for our current understanding of the organization of elements.
Mendeleev studied the properties of elements and looked for?
Patterns
Who is Demetri Mendeleev?
Dmitri Mendeleev was a Russian scientist who is credited with creating the periodic table of elements in 1869. He arranged the elements in order of increasing atomic mass and noticed patterns in their properties which led to the periodic law. Mendeleev's work laid the foundation for modern chemistry.

Who noticed that the chemical properties of elements increased in a periodic manner?
Dmitri Mendeleev, a Russian chemist, noticed that the chemical properties of elements increased in a periodic manner and arranged them into the periodic table in the 1860s. Mendeleev's periodic table was based on atomic mass and led to the development of the modern periodic table based on atomic number.
Who arranged the periodic table according to increase in atomic weights?
Dmitri Mendeleev, a Russian scientist. He arranged cards in atomic weight order and noticed patterns (periods). This resulted in him being able to guess which elements were missing and complete the periodic table.
What similarities and difference exist in the the arrangement of the elements made by Dmitri mendeleev and lothar Meyer?
Both Mendeleev and Meyer arranged the elements in order of increasing atomic weight and noticed patterns in the properties of the elements. The main difference is that Mendeleev's periodic table included gaps for undiscovered elements, predicted their properties accurately, and left space for new elements to be added later. Meyer's periodic table did not have this predictive aspect.

Who first arranged the elements according to atomic mass and noticed a periodic recurrence of their physical and chemical properties?
Dmitri Mendeleev
What pattern did Mendeleev arrange elements in?
Dmitri Mendeleev arranged the elements in his periodic table in order of increasing atomic mass and grouped elements with similar properties together. This arrangement helped him to identify periodic trends and predict the properties of undiscovered elements.
