How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
Why did mendeleevs periodic table only have 63 elements on it?
Mendeleev's periodic table contained 63 elements because it was based on the elements known at the time, which were primarily discovered in the 19th century. Mendeleev organized these elements by increasing atomic mass and grouped them according to similar chemical properties. His table was groundbreaking, but many elements that exist today had not yet been discovered or isolated when he published his work in 1869. Additionally, the understanding of atomic structure and the periodic law evolved over time, leading to the discovery of new elements and the eventual expansion of the periodic table.
What are the most metals on the periodic table?
There are 91 metals in the periodic table today, but new ones are added as time passes.
Modern periodic table is invented by?
The modern periodic table was invented by Dmitri Mendeleev in 1869. Mendeleev organized the elements by increasing atomic mass and grouped them based on similar chemical properties, which laid the foundation for the periodic table we use today.
Father of the periodic table?
Dmitri Mendeleev is known as the father of the periodic table. He developed the periodic table by arranging elements based on their atomic mass and chemical properties, establishing the foundation for the modern periodic table used today. Mendeleev's table had gaps for undiscovered elements, which were later found and filled, validating his organization of the elements.

What was Mendeleevs proposal?
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
What did Mendeleevs periodic table look like?
It looks the same as it did when Mendeleev created it. There are no changes made to the table throughout the years because Mendeleev had predicted the correct placement for all of our current known elements.

Who uses the periodic table today?
Chemists
What are the most metals on the periodic table?

Who was the scientist that organized the elements into a table that you use today and what was the table called?
i don't know the scientist but it is the periodic table of the elements
How does the periodic table relate to anything going on in the world today?
well every known materialthat we asociate with is listed in the periodic table.
Who rearrange the periodic table by atomic number into the table you recognize today?
Henry Moseley
Who is the inventor of the periodic table you use today?
Dmitri Mendeleev.
What did Dmitri Mendeleev discover?
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
What was the first periodic table?
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
