devised an early form of periodic table‚ which he called the telluric helix. | John Newlands | Classified the 56 elements that had been discovered at the time into eleven groups which were based on similar physical properties. He also noted that many pairs of similar elements existed which differed by some multiple of eight in mass number‚ and was the first person to assign them an atomic number. | Dmitri Mendeleev | The first scientist to make a periodic table much like the one we use today.
