Mendeleev arranged the elements by increasing Atomic Mass instead of like today by increasing atomic number.
Mendeleev arranged the periodic table of elements according to the atom's number of protons.
Mendeleev arranged the known chemical elements in a table according to increasing mass.
Atomic Mass
True
increasing atomic mass.
Atomic Mass & Chemical Reactivity
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 the periodic table according to their atomic masses.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.
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.
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
Mendeleev arranged elements in order of atomic mass. He arranged elements in rows and columns that later helped in discovering modern periodic table.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
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 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 them in the increasing order of atomic mass.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
mendelev arranged the elements in the periodic table in the asending order of the mass number of elements.
Dmitri Mendeleev arranged elements in order of increasing atomic masses. He placed elements in rows and columns.
Niels Bohr: the modern periodic table where the elements are arranged in the increasing order of atomic number Mendeleev: The periodic table where the elements are arranged in the increasing order of atomic mass
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.
