From 1863 to 1866, English chemist John Newlands wrote a series of papers explaining similar properties of elements recurring at intervals of eight, which became known as the Law of Octaves.In 1864, German chemist Julius Lothar Meyer published a table with 28 elements while English chemist William Odling published a table of 57 elements.In 1862, French geologist Alexandre-Emile Beguyer de Chancourtois published the “telluric screw” which is a three-dimensional arrangement of the elements.In 1857, French chemist Jean-Baptiste Dumas described relationships between groups of metals in his published work.In 1843, German chemist Leopold Gmelin produced a table of 55 elements which is one of the foundations of our modern periodic table.In 1829, German chemist Johann Wolfgang Döbereiner discovered that the elements can be grouped into triads based on their chemical properties, which became known as the Law of Triads.In the following century, chemists continued to research and observe relationships of the elements and develop one scheme that unites these relationships.French chemist Antoine-Laurent de Lavoisier came up with the first list of chemical elements in 1789.The elements are also arranged according to atomic number, electron configuration, ionization energy, electronegativity, electron affinity, and metallic character.The elements are arranged in columns (called groups), rows (called periods), and specific rectangular areas (called blocks).The other 24 were synthesized in laboratories.

As of 2019, there are 118 identified chemical elements.Chemical elements are materials that cannot be broken down through chemical methods.
