The Development of the Periodic Table

The Development of the Periodic Table Although Dimmit Mendel is often considered the ‘father’ of the periodic table, the work of many scientists contributed to its present form. Between 1817-1829, Johann Doberman began to group elements with similar properties in to groups of three or triads. This began when he noticed that the atomic weights of strontium (Sir) were halfway between Calcium (Ca) and Barium (Baa). He stated that nature contained triads of elements In which the middle element had properties that were an average of the other two elements.
In 1 863, John Newlyweds, an English chemist, proposed the Law of Octaves, which dated that elements repeated their chemical properties every eighth element. The musical analogy was laughed mocked at the time, but was found to be Insightful after the work of Mendel and Meyer was published. In 1867, Dimmit Mendel was teaching what we now call “General chemistry” at the university of SST. Petersburg. Since he didn’t like any of the available textbooks, he decided to write one of his own.
When he arranged the elements in order of atomic weight, he found that the elements lined up naturally unto groups and families with similar properties. In 1 869, Lothario Meyer published a preliminary list of 28 elements, and was the iris to classify elements into 6 families according to their valence (The combining capacity of an element determined by the number of electrons that it will lose, add, or share when it reacts with other atoms).

In 1894, Sir William Ramsey removed oxygen, nitrogen, water and carbon dioxide from a sample of air and was left with a gas 19 times heavier than hydrogen and very enervative. He called this gas argon. He went on to discover more of what we know call noble gases, and was awarded the Nobel Prize in Chemistry in 1904. In 1913, Henry Mosey found a relationship between an elements X-ray wavelength and its atomic number. Moseys discovery showed that atomic numbers were not arbitrary but had an experimentally measurable basis.
He also predicted new elements.
