Mendeleev arranged his periodic table by order of increasing:
A) elemental volume.
B) proton count.
C) elemental mass.
D) elemental size.
Elemental Mass
The mass of a single atom of an element, typically measured in atomic mass units (amu) or grams per mole.
Periodic Table
A tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties.
Proton Count
The number of protons in the nucleus of an atom, which determines the chemical element of the atom and is denoted as the atomic number.

Final Answer :
C
Explanation :
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass, which is closely related to the number of protons and neutrons in an atom's nucleus. This organization allowed him to predict the properties of elements that had not yet been discovered.
