Mendeleev arranged the elements according to their atomic weight and valence.
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.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
He arranged elements in order of increasing atomic masses. He left gaps for undiscovered elements.The elements with same properties were grouped together.
He did order it in the periodic table, but i think what your looking for is that he arranged it in order of increasing Atomic mass

Mendeleev arranged the elements in the periodic table according to their atomic masses.
your mums atomic acid
He arranged the elements in the increasing order of atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.
increasing Proton number.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Mendeleev is usually credited as the first person to do so. Subsequently, chemists learned to arrange the elements by atomic number rather than atomic mass.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
