This chemist was Dmitri Mendeleev in 1869; the arrangement is based on the law of periodicity.
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.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
No. When the elements are arranged in order of increasing atomic number there is a periodic repetition of their physical and chemical properties.
The modern version of the periodic table is arranged according to the atomic number.
No. The modern periodic table is arranged in accordance to increasing atomic number and repeating properties.
The elements on the modern periodic table are arranged based on the increasing order of atomic number and repeating properties.
by groups and periods
Atomic number
Modern Periodic Law.
The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
In modern periodic table, elements are listed by increasing atomic number.
