Why did Mendeleev set up and predict about the periodic table?

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?
he measerd elements by atomic weight and/or mass
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.)
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
He perfected the arrangement of the periodic table?
The periodic table is more like a collaborated set of work. Mendeleev started by arranging the elements by properties and mass. Then, Henry Moseley arranged it by atomic number and properties, which is what we use today. Then, Noble Gases were discovered, and those were added in. If you look at the periodic table, it's mostly arranged by mass, too. However, it's, of course, arranged by proton number.

In what century was the periodic table set up?
The periodic table was created in the 19th century by Dmitri Mendeleev
How did Dmitri Mendeleev set up the periodic table by?
in order of atomic mass
How did Mendeleev set up the periodic table?
he measerd elements by atomic weight and/or mass
What type of scientist was Dmitri mendeleev?
Dmitri Mendeleev was a chemist who is best known for being the first one to sort and set up the Periodic Table of 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 did Mendeleev set up the periodic table the way he did?
Because he was creating a book called the Principle of Chemistry and he noticed the pattern in every elment. So he made a table or (chart) called Periodic Table of Elements.
What does the periodic tabel mean?
The periodic table is an arrangement of the elements by atomic number. It was made by Dmitri (Deh-Mee-Tri) Mendeleev (Men-Del-Leh-Av) The set-up and the specific details vary due to the different types of tables.
What would have happened if Dmitri mendeleev hadn't created the periodic table?
someone else probably would have by now, although depending on how long it took, modern science could be set back years
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
Are the groups of the periodic table set up in columns or rows?
The vertical columns in a periodic table are called Groups.
