First we have to understand what an element is. The periodic table came about through attempts by people to group elements according to their chemical properties. He decided to try to keep the pattern by saving spaces for elements that weren't discovered yet. The Periodic Table of Elements is a chart created by Dmitri Mendeleev in 1869 to help organize the elements that had been discovered at that time. Like Meyer, he trained under Robert Bunsen and used similar techniques to complete the table. Spaces were left blank for missing/unknown elements at the time.

Johann Dobereiner- Model of Triads Dobereiner catergorised elements with similar characteristics into groups of threes. The periodic table of elements took many years and the work of many scientists to become what it is today. In 1864, a german chemist named lothar meyer demonstrated the connection between atomic mass and elemental properties an early version of the periodic table with 28 elements organised by valence, which is the order of the quality that will determine the number of atoms with any single atom or group will unite chemically. Moseley used this to show that atomic number, not atomic weight was most important in grouping and ordering the elements.
