Periodic Table of Elements

It is a tabular arrangement of the elements based on increasing atomic number.

He arranged the elements in the periodic table according to atomic numbers.

• Dmitri Mendeleev

• John Newlands

• Henry Moseley

• Johann Dobereiner

He was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves.

• Dmitri Mendeleev

• John Newlands

• Johann Dobereiner

• Henry Moseley

The Father of the Periodic Table of Elements. He is considered to be the most important contributor to the development of the periodic table. His version of the periodic table organized elements into rows according to their atomic mass and into columns based on chemical and physical properties.
