increasing Proton number.
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Dmitri arranged elements in order of increasing atomic masses. He considered chemical properties of the elements.
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
He made flashcards of elements and organized them in order of increasing atomic mass.
increasing Proton number.
Dmitri arranged elements in rows and columns. According to him, the properties of elements are periodic functions of their atomic weights.
Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
Dmitri Mendeleev
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
"When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties" is a statement of the periodic law.
Dmitri arranged elements in order of increasing atomic masses. He considered chemical properties of the elements.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
He used an atomic mass, and also an atomic mass of units. Therefore he was able to find the pattern. I got this answer off of Mr. Kebblers class.
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
