he ordered the known elements according to Atomic Mass, which worked out for the most part, until later another scientist came along and realized it worked out even better if arranged according to atomic number (number of protons)

What was Dmitri Mendeleev's accomplishments?
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
How did Mendeleev set up the periodic table?
Mendeleev arranged elements in order of increasing atomic mass and grouped them based on similarities in their chemical properties. Gaps were left for undiscovered elements, and he predicted their properties based on the patterns he observed in the table. Mendeleev's arrangement formed the basis of the modern periodic table.
Did Mendeleev end each row in his periodic table with an inert gas?
No, Mendeleev did not end each row in his periodic table with an inert gas. At the time he created his periodic table in 1869, the noble gases (inert gases) had not yet been discovered. Mendeleev's table focused on the properties of the elements known at that time and arranged them according to their atomic weights, with elements exhibiting similar chemical properties grouped together, but it did not include a complete set of noble gases.
Who constructed the periodic table of elements?
Dmitri Mendeleev constructed the periodic table of elements in 1869 based on atomic mass( which is how much an atom weighs). this however was changed many many years later resulting in our current design of the periodic table which is based on atomic number instead.( the number of protons in an atom.)
Why mendeleev succeeded where others failed?
Mendeleev succeeded in creating the periodic table because he organized elements by increasing atomic mass and recognized patterns in their properties, allowing him to predict the existence and characteristics of undiscovered elements. His willingness to leave gaps for unknown elements demonstrated his confidence in the periodic nature of elements, which others had overlooked. Additionally, Mendeleev's approach combined both experimental data and theoretical insights, enabling a more comprehensive understanding of elemental relationships. This innovative thinking set his work apart from that of his contemporaries.
In what century was the periodic table set up?
The periodic table was set up in the 19th century, specifically in 1869 by Dmitri Mendeleev. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table.
What was Dmitri Mendeleev's accomplishments?
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages ​​and that was a textbook for many years.
When did Dmitri set up the periodic table?
Dmitri Mendeleev set up the periodic table in 1869. He organized the elements based on their properties and atomic weights.
What type of scientist was Dmitri mendeleev?
Dmitri Mendeleev was a Russian chemist and inventor who is best known for formulating the Periodic Law and creating the periodic table of elements. He is considered the "father of the periodic table" for his contributions to the field of chemistry.

Who is a Russian scientist who discovered a set of patterns that applied to all elements?
Dmitri Mendeleev, a Russian chemist, discovered the periodic law and created the periodic table of elements in 1869. Mendeleev's table arranged elements based on their atomic mass and predicted the existence and properties of undiscovered elements.
How did Dmitri Mendeleev set up the periodic table by?
Dmitri Mendeleev arranged the elements in the periodic table based on increasing atomic mass, while also grouping elements with similar properties together. This allowed him to identify patterns and gaps in the elements' properties, which led to the creation of a periodic law that predicted the properties of undiscovered elements.
Dmitri was what type of scientist?
Dmitri Mendeleev was a chemist who is best known for being the first one to sort and set up the Periodic Table of Elements.
Why mendeleev succeeded where others failed?

This innovative thinking set his work apart from that of his contemporaries.
Did Mendeleev noticed a definite pattern in the valence of the elements?
the samepattern for how many protons all elements have to they are all factors of each other. That is why the periodic table is set up the way it is in that awkward shape
