There are theoretically much smaller constituents of an atom, but this is only theory.

When the elements were arranged in order of increasing atomic mass?
in 1869 by Dmitri Mendeleev
How was periodic table organized?
He organized the elements by the increasing order of the atomic mass.
What determined the order of elements across a row in Mendeleev's periodic table?
Increasing Mass
How did Mendeleev orangize the elements in to the periodic table?
He arranged them in the increasing order of atomic mass.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
Rank the pairs of masses in order of increasing magnitude of gravitational force betweenthe masses?
As you increase the mass the magnitude of the gravitational force will increase as well.
Who is Dmitri Mendeleev?
He proposed one of the early versions of the Periodic Table. He arranged the elements in the increasing order of their increasing Atomic Mass and repeating properties.
Was a chemist who arranged the known elements in order of increasing atomic mass?
Mendeleev
When the elements were arranged in order of increasing atomic mass?
in 1869 by Dmitri Mendeleev
How was periodic table organized?
He organized the elements by the increasing order of the atomic mass.
Do elements all have the same mass?
No, look at any periodic table and you will see they are arranged in order of increasing mass.
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
Why does Atomic mass on the periodic table progressively changes left to?
Because the number of protons, neutrons and electrons in atoms is increasing to left.
What was mendeleev able to do with the properties and mass numbers?
He arranged the elements in the increasing order of atomic mass and repeating periodic properties.
What determined the order of elements across a row in Mendeleev's periodic table?
Increasing Mass
