The first periodic table was put in order of atomic mass, not atomic number.


Dimitri Mendeleev. But it didnt look like the periodic table we use today.


The Periodic Table was put together by a Russian college professer named Dmitri Mendeleev. He did it to help his students remember the elements that were on the table at the time.


The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today.


wwhy was the periodic table put together? The Periodic Table is very helpful to chemists, physicists, and other scientists because it helps to categorize the behavior of the elements in the table. For example, you can expect elements with the same number of protons in the nucleus of an atom to behave in similar ways. Thus, elements with the same number of protons are kept in the same column of the table. Nice!


Because they are not elements. They are combinations of different elements put together.


in ascending order by atomic number (number of protons) of an atom of a particular element. previously, the periodic table had elements ordered by atomic mass.


Dmitri Mendeleev is credited with the first periodic table


The columns of the periodic table bring together elements with similar properties.


Metals are grouped together to the left of the Periodic table.


There is a group of elements in the periodic table as the elements with same properties are clubbed together.


Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.


elements are found on the periodic table compounds are two or more elements put together to make a compound


There is a line in the periodic table that separates the metals and the non-metals.


The rows on a periodic table is called alkali metals. All together there are 18 groups.


Periodic table is an arrangement of elements where the elements are arranged in the increasing order of their atomic number. The atoms on the periodic table are not held by any force.


Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.


Because the atom can have the same structure as another atom and those can be together on the periodic table.


Periodic table groups elements with same properties together. It makes the study of elements easier.


Periodic table group elements with same properties together. Hence their properties can be identified.


the periodic table is grouped according to similarities. when Mendeleev grouped his first periodic table they followed a pattern. any elements that contained similarities they were all put into the same column.


Dmitri Mendeleev in 1869; but because the history of this discovery is more complicate see the link below.


The periodic table is made up of elements. Elements bond together with each other to form molecules, but there are no molecules on the periodic table. An example of a molecule would be carbon dioxide, CO2 which is made up of carbon and oxygen, both of which are on the periodic table.


It is meant some of the elements in the periodic table put into a group! The vertical columns in the periodic table are called groups


Metallic elements are grouped together on the periodic table. They are found in group 1A and are down the left side.
