Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
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.
Mendeleev's table was also based upon his Periodic Law, which stated that when elements are arranged by increasing atomic number, there is a periodic repetition of similar chemical and physical properties.
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.
Mendeleev arranged elements in order of atomic mass. He arranged elements in rows and columns that later helped in discovering modern periodic table.
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
He arranged them in the increasing order of atomic mass.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Dmitri Mendeleev arranged elements in order of increasing atomic masses. He placed elements in rows and columns.
Mendeleev arranged elements in order of increasing atomic masses. He found properties to be periodic when arranged in this manner. The elements with same chemical properties were grouped together.
mendelev arranged the elements in the periodic table in the asending order of the mass number of elements.
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
