Mendeleev created his Periodic Table at the time when presence of sub-atomic particles like electrons, protons and neutrons were not discovered.So, the term atomic number was not known till now.
So , he positioned the elements in increasing order of atomic mass because Atomic Mass of many elements discovered till then were known.
What else can I help you with?
Which property did Mendeleev primarily use to classify the element?
Mendeleev primarily used the element's atomic mass to classify them. He organized the elements into a periodic table based on their increasing atomic mass, allowing him to predict the properties of missing elements and arrange them in a logical order.
What property did Medeleev position the elements?
Mendeleev positioned the elements primarily based on their atomic mass and their chemical properties. He arranged them in a periodic table format, grouping elements with similar properties into columns, which allowed him to predict the existence and properties of undiscovered elements. This arrangement highlighted the periodic trends in element behavior, demonstrating that properties recur at regular intervals when elements are ordered by increasing atomic mass.
How are the properties displayed in the periodic table?
Elements with same property are grouped together. Property can be estimated by its position.
Which is a property that Mendeleev's predicted for gallium?
Examples: density, melting point, atomic weight, density and formula of oxide.
What other element from fifth period has similar property to oxygen?
Oxygen is placed in the second period of the Mendeleev table.
What property did mendeleev arrange the elements?
Atomic Mass.
What property was Mendeleev's table was base on?
Known elements were arranged by increasing mass.
What property did mendeleev position the elements on the periodic table?

What physical property did Mendeleev use to places the element in rows on the periodic table?
Mendeleev used the increasing atomic mass of elements to arrange them in rows on the periodic table. This allowed for elements with similar properties to be grouped together and for the gaps to be left for undiscovered elements.

What is a property that Mendeleev predicted for gallium Ga metal gas nonmetal or highly reactive?
Mendeleev predicted that gallium (Ga) would have properties of a metal based on its position in the periodic table. Gallium exhibits characteristics of a metal, such as being solid at room temperature, having a metallic luster, and conducting electricity.
Who gave the modern periodic table so?
The modern periodic table was created by Dmitri Mendeleev in 1869. He arranged the elements based on increasing atomic mass and similar chemical properties. Mendeleev's table provided a framework for organizing the known elements and predicting the properties of undiscovered elements.
What property did Mendeleev use to primarily the elements into a periodic table?
The basic organization structure was by atomic mass, which while it may follow a trend of increasing with each progressing element on the modern table, which is organized by atomic number or number of protons, there are a few exceptions, such as Argon having a greater atomic mass than Potassium, even though Argon has one less proton.
By what property did Mendeleev suggest that the periodic table be arranged?
Madeleev originally arranged the elements in the first periodic table by their average atomic masses. Later it was changed to atomic number by Moseley, or the number of protons each of that element's atom has.
What does Mendeleev's periodic law stated?
physical and chemical properties are the fundamental property of d Atomic Mass.This law was stated in d year 1869.
