Mendeleev positioned the elements primarily based on their Atomic Mass and their chemical properties. He arranged them in a Periodic Table format, grouping elements with similar properties into columns, which allowed him to predict the existence and properties of undiscovered elements. This arrangement highlighted the periodic trends in element behavior, demonstrating that properties recur at regular intervals when elements are ordered by increasing atomic mass.
Elements with same property are grouped together. Property can be estimated by its position.

Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Dmitri Mendeleev arranged the elements in his periodic table by increasing atomic mass because he noticed a periodic pattern in properties repeating every 8th element. This arrangement allowed him to predict the properties of undiscovered elements and left gaps for them in his table.

Dmitri arranged elements in rows and columns. According to him, the properties of elements are periodic functions of their atomic weights.

It's probably Mendeleev you're after. He came up with the first version of a Periodic Table of the elements, and used this to predict the properties of elements that hadn't been discovered at that time.
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
the number of protons in the nucleus and the number of electrons in the valence orbital
Before Mendeleev, Dobereiner, De-chancourtis, Newland and Lother Meyers had already given their respective periodic arrangement of elements, but none of the models were accepted as they had many limitations...
atomic no. or basically according to the no. of electrons in their outermost shell whcih reflect the property of individual atom
he based it on his favourite game
