in 400bc they useds the words atom and element and had the elements of earth water fire and air and they used that to explain "world stuff"
The Four Element Theory: that everything was made up of either Fire, Earth, Water and Air
none, his concept of atoms was totally different.
the greek thinkers had a big impact as they were part of the Periodic Table and the name of a main greek thinker was fredric billyone.
A Periodic table The Periodic Table of the Elements.
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
who introduced the first Periodic Table
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
Moseley proposed a strictly rational periodic table.

atomic number
Moseley was the person who found that the periodicity directly relates with the atomic number of elements.

He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
Mosley arranged elements in order of increasing atomic number
A group in Periodic Table is the column of element in periodic table
It is called the Periodic Table of Elements.

No, it is not on the periodic table.
