Dmitri Mendeleev
Dmitri Mendeleev came up with the modern Periodic Table in 1869.
Many attempts were made by Dobereiner , Newlands and Mendeleev in initial stages. Later on , the idea of arranging elements in increasing atomic number came up which is the today's periodic table.
the same one who invented it
The periodic table is entirely made up of elements.
Dmitri Mendeleev
The very first periodic table was created by Dmitri Mendeleev and was based mainly on atomic masses. The modern periodic table was designed by Henry Moseley and is based not only on atomic masses but also their chemical and physical properties.
The Periodic Table is arranged like it is for a specific reason. It is probably called the Periodic Table because it is made up of "periods" or horizontal rows.
no - gases are few in number - metals make up most of the periodic table
a little less. but the periodic table is made up of mostly metals
The periodic table has 7 rows and 32 columns.
The periodic table lists element and not minerals.
Ammonia is not on the periodic table. It is a compound, not an element.
