The Periodic Table has 18 groups and 7 periods.
These elements are termed as 'lanthanides' and 'actinides' have certain different characteristics that cannot be fitted into modern periodic table,hence they are placed at the bottom.
Dmitri Mendelev was a Russian scientist who created the first modern periodic table of elements.
It groups together elements with similar properties.
You think to Dimitri Mendeleev, inventor of the modern periodic table of elements.
The periodic table was first proposed by a Russian chemist Dimitri Mendeleev. The modern periodic table ordered by atomic number was proposed by an English physicist, Henry Moseley.
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
