Mendeleev organized the elements by Atomic Mass. It was later discovered that organizing them by atomic number created a more accurate and logical Periodic Table.

How did chemists change Mendeleev's periodic table in early 1900s?
They used atomic number instead of Atomic Mass to organize the elements.
What properties of elements did mendeleev list as he began to organize the elements?
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
What method did Mendeleev use to organize the periodic table of elements?
An element's atomic number, or how many protons it has.
What method did Dmitri Mendeleev use to organize the periodic table of elements?
Atomic weight.
What periodic trends did Mendeleev organize his periodic table by Atomic number Atomic mass Octaves Triads First ionization energy?
Mendeleev organized his periodic table by atomic mass, grouping elements with similar properties into columns. He also observed patterns in properties repeating every 8 elements, known as octaves. Triads were used to group elements with similar chemical properties into sets of three, based on their atomic mass. Mendeleev did not specifically organize his table by atomic number or first ionization energy.
Which was NOT used by Mendeleev to organize his periodic table?
Atomic number was not used by Mendeleev to organize his periodic table. He organized the elements based on their atomic mass and properties, leaving gaps for undiscovered elements that were later filled.

Did Dmitri Mendeleev organize elements by atomic numbers or atomic mass?
At first, he did it by atomic mass, but that didn't quite work out right, so he changed it to atomic number.
Who created the way to sort elements?
Dmitri Mendeleev is credited with creating the periodic table, which is a systematic way to organize elements based on their properties and atomic number.
What method did Mendeleev use to organize the periodic table of elements?
An element's atomic number, or how many protons it has.
How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
What method did Dmitri Mendeleev use to organize the periodic table of elements?
Atomic weight.
How are the modern table arranged differ than Mendeleev's table?
Mendeleev arranged the elements in order of increasing atomic mass.Moseley arranged the elements in order of increasing atomic number.

Mendeleev did not specifically organize his table by atomic number or first ionization energy.
Who improved the periodic table?
Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
Mendeleev arranged the elements in his periodic table in order of?
Mendeleev arranged the elements in his periodic table in order of increasing atomic mass while also grouping elements with similar properties together. His periodic table laid the foundation for the modern periodic table we use today.
