Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third‚ all the atoms were different from all the other atoms. Fourth‚ atoms of different elements combined together in equal numbers to form compounds. Fifth and final

Within the table‚ elements with similar Mass are placed together in groups. Like other chemists‚ such as Newlands‚ Mendeleev listed elements in order of Properties but he realised that he need to leave Gaps for elements that had not yet been Discovered. Why did Newlands’ fellow scientists

and created the first geometrical representation of the periodic table. John Newlands proposed the Law of Octaves which states the elements repeat the chemical properties after every eighth element. Lothar Meyer and Demetriv Mendeleev published their own periodic table. Mendeleev arranged the elements in order of increasing atomic weight and grouped the elements of similar properties together. William Ramsay and Lord Rayleigh discovered the noble gases‚ which were added to the periodic table as group

He is most noted for his contributions to molecular theory‚ including what is known as Avogadro’s law. In tribute to him‚ the number of elementary entities (atoms‚ molecules‚ ions or other particles) in 1 mole of a substance‚ 6.02214179(30)×1023‚ is known as the Avogadro constant.
