He mostly used this:

-How much Atomic Mass (at first he used this method but he later corrected it to this:)

-atomic number or the number of protons

He used this to determined the order of the Periodic Table together:)

How did Mendeleev place germanium on the periodic table?

Mendeleev was able to predict the properties of the yet unknown element (Germanium) by the properties of the surrounding known elements on his periodic table of the elements. Predicting properties such as reactivity, density, atomic mass, etc., he knew where the undiscovered element would be placed.


How did Mendeleev drcide where to place arsenic and selenium on the periodic table?

Mendeleev placed arsenic and selenium on the periodic table based on their chemical properties and atomic masses. He arranged elements by increasing atomic mass and grouped them by similar properties. By doing so, he could predict the properties of undiscovered elements and fill in gaps in the periodic table.


Why Mendeleev put more than one element in one place?

Mendeleev put more than one element in one place, called a group or family, based on similarities in their chemical properties. This structure allowed him to predict the properties of undiscovered elements and accurately organize the periodic table. Grouping elements with similar properties together made it easier to understand their relationships and behavior.


What place order was Dmitri mendeleev in?

Dmitri Mendeleev was the first to create a widely recognized periodic table of elements in 1869. His arrangement was based on atomic mass and chemical properties, allowing for the prediction of undiscovered elements. While he was not the first to arrange elements, his table's systematic nature and the foresight of placing gaps for missing elements marked a significant advancement in chemistry. Mendeleev's work ultimately laid the foundation for the modern periodic table, which is organized by atomic number rather than atomic mass.


How did Mendeleev decide where to place arsenic and selenium?

Dmitri Mendeleev placed arsenic and selenium in his periodic table based on their chemical properties and similarities to other elements. He prioritized their behavior and valence over atomic mass, which led him to position them in a way that reflected their similarities with phosphorus and sulfur, respectively. This placement allowed him to maintain the periodic trends he observed, even if it meant deviating from a strict order by atomic mass. Mendeleev's decisions were guided by the idea that elements with similar properties should be grouped together.

Why did Mendeleev place iodine in the same group as fluorine?

Mendeleev placed iodine in the same group as fluorine because both elements have similar chemical properties, such as forming compounds with similar stoichiometry and showing similar reactivity patterns. This classification allowed Mendeleev to identify a pattern in the properties of elements and lay the foundation for the modern periodic 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.

What inspired Mendeleev to create his organization for the elements?

Mendeleev, a Russian chemist, organized the periodic table in order of relative atomic mass. He realized that the physical and chemical properties of chemicals were related to their atomic mass, and arranged them in a way so that groups of elements with similar properties fell into vertical columns (groups) with each period's elements having incrementally greater mass than the masses of the elements in the periods above it.According to Mendeleev, he had a dream about the elements falling into place on a table. His work was partly based on the work of Anton Lavoisier, who discovered the role of oxygenin combustion, and gave the element its modern name.

Why did Mendeleev swap Tellurium and Iodine around?

Mendeleev swapped Tellurium and Iodine in his periodic table to maintain the chemical properties of elements within the same group. Even though Tellurium has a higher atomic mass than Iodine, their chemical properties are more similar when placed in the switched positions, following Mendeleev's periodic law.


Who arrange the periodic table of elements?

the place where an element sits on a periodic table is not chosen by anyone. the place where it sits is chosen by it's atomic number or the number of protons it has eg lithium 3 protons its third


What is mendeleev's quotation?

Dmitri Mendeleev's famous quotation is: "I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper." This quote refers to the dream Mendeleev had where he visualized the periodic table of elements, which he later developed and organized based on atomic mass.


Did mendeleev's original table could accommodate elements that did not even exist?

Yes, Mendeleev's original periodic table had gaps to accommodate elements that were yet to be discovered. He even successfully predicted the properties of some of these missing elements based on his table's structure.
